One lesson that has served me well over the years: Don’t carry bad blood. In any long career you will be misunderstood. You’ll disagree. You’ll feel wronged. Sometimes even betrayed. Decisions won’t go your way. People will make calls you don’t agree with. The temptation is to keep score. But resentment is expensive. It clouds judgment. It narrows perspective. It limits future opportunity and is neither rational nor helpful. I’ve learned that making things right is both good relational practice and good business practice. Industries are small. Reputations compound. People you disagree with today may become partners tomorrow. And often, when you sit down and have the hard conversation, you discover the situation was more complex than you initially believed. There is real freedom in choosing not to carry offense. In picking up the phone and saying, “Let’s reset.” Over time, it builds a network of people who know you value relationships. Early in my career I valued results over relationships. Now, I know relationships trump results. Relationships are far more enduring and valuable than the near term results I used to favor. That’s good for business. More importantly, it’s good for the soul.

It takes one minute to damage a career you spent 30 years building. Because success isn’t about skill or intelligence. It’s about emotional regulation. Exercising restraint instead of: → Engaging in a heated debate with a client. → Exchanging a sharp word with a colleague. → Sending an angry email in the heat of the moment. The second you lose control, you’ve lost. Emotional regulation is the biggest marker of career success. The good news is it’s a muscle you can build. Here's how: 1. Know Your Triggers → Identify what sets you off. → Do you feel threatened when criticised? → Awareness is the first step to control. 2. Hit Pause → Before reacting, ask yourself: What are the consequences of my move? → Regret minimisation is critical. 3. Reframe the Experience → What else could this mean? → Maybe the person was having a bad day. → Chose an interpretation that serves you. 4. Create a Delay on Emails Sent → Set a 10-minute delay on all outgoing emails. → This in and of itself could save your career. 5. Breathe → When emotions rise, take three slow breaths. → It signals your nervous system to reset. → Simple, but powerful. 6. Speak With Emotional Intelligence → Once you’re ready to respond, choose your words carefully. → Ask: How can I create the right outcome in a calm way? Remember: → If you choose restraint, you win. → If you reframe, you grow. And every time you stay in control, you keep your power. How important do you think emotional regulation is for career success? ---- ☀️Follow Deena Priest for career, leadership and personal development insights.

It’s simple math 🧐 I use to think that motivation was the key to monumental success. Long story short, it’s not. It’s about the little things you do every day that will take you from reasonable to slightly unreasonable to completely unreasonable progress. Your future is not defined by how motivated you are, but by your daily routines and systems. I believe in this so much that we named our company Butterfly 3ffect to reflect the value of incremental gains. we believe that that’s how the best people and brands grow. Here’s how you grow the small way: 1. Start by setting achievable goals, like reading one chapter of a book each day or going for a short walk 2. Practice gratitude by writing down three things you're thankful for every night before bed 3. Engage in daily self-reflection, even if it's just for a few minutes, to assess your thoughts and actions 4. Incorporate small acts of kindness into your daily routine, like holding the door for someone or offering a genuine compliment 5. Learn something new every day, whether it's a fun fact, a new word, or a new skill 6. Prioritise self-care by getting enough sleep, staying hydrated, and taking breaks when needed 7. Surround yourself with positive influences, whether it's uplifting books, supportive friends, or inspiring podcasts 8. Embrace failure as a learning opportunity and a stepping stone to growth 9. Stay consistent and patient, knowing that small progress over time adds up to significant improvement 10. Celebrate your achievements, no matter how small, to stay motivated and encouraged along the way.

🧑🏽 Designing Better Personalization UX. With guidelines on how to better tailor content and features to user’s needs and interests. ✅ Customization allows users to choose exactly what they want. ✅ Personalization anticipates what they want behind the scenes. ✅ We personalize to match specific needs without user’s effort. ✅ We allow users to customize preferences, filters, layout, data. 🤔 But often only very few people customize their experience. 🚫 Past behavior doesn’t always predict future actions. 🤔 Users often have different needs at different times. ✅ Design a wide range of presets, templates and defaults. ✅ Track frequent actions and errors, and suggest shortcuts. ✅ Always add content, or reshuffle it, rather than removing it. ✅ Expose users to non-matching topics to avoid filter bubbles. 🤔 Often users don’t know what they need, or what they’d like. ✅ Good personalization is deeply embedded in a user journey. ✅ Search for moments when you want to win user’s attention. ✅ Ask users explicitly about their intent to learn their context. ✅ Let users override personalization if it goes against their needs. ✅ When journey breaks, don’t stitch it, but tie a beautiful bow. We can’t personalize without research. Collect reliable data about users first. Then segment users into groups with shared needs. Decide what messages you have for each group. And define a user model, content model and metadata that go along with it. Then decide on individual or role-based personalization. Choose touchpoints where personalized UX will be served. Apply the logic across your channels, but give users full control of their data. In that process, define how the team will test and measure the impact of personalization over time. Such a project might often feel like a huge leap of faith without immediate benefits. But if done well, it can increase customer lifetime value significantly — but you will need short-term victories to get a long-term commitment. So start slowly. Run experiments. Personalize where you can make the highest impact. More often than not, the outcome will be worth the effort — even although most users will never even notice it, they might stay for many years to come. ✤ Useful resources Personalization Pyramid, by Colin A.

🏃♀️ Imagine a study on marathon performance that doesn't mention some runners are carrying 50-pound backpacks. That's the 2025 Women in the Workplace report from Mckinsey and LeanIn 60 pages on why women "want promotions less." Zero mentions of childcare, eldercare, or the invisible second shift. Their own data shows women and men are equally committed to their careers, over 90% on every measure. Young women under 30 has even more ambitious than young men. Latinas are the most ambitious group in the entire study. 🤔 So where does this "ambition gap" come from? Buried on page 10, in a small box, they note that women who decline promotion cite "personal obligations" at nearly double the rate of men. Then they move on. No follow-up. No analysis. No asking the obvious question: What are these "personal obligations"? 💔 I'll tell you what they are. 👉 They're the 2am feeding before your 8am presentation. 👉 The school pickup that can't be rescheduled. 👉 The elderly parent who needs a doctor's appointment during your board meeting. 👉 The mental load of remembering everyone's everything while being told you "lack ambition." The report measured ambition without measuring the invisible infrastructure women are running at home. 👉 Here's what the report should have asked: ⁉️ Do women with equal childcare support want promotions at the same rate as men? ⁉️ Do women with flexible work arrangements show the same career drive? ⁉️ Does the "ambition gap" exist in countries with subsidized childcare? (Spoiler: Research says no, no, and no.) Instead, they concluded women are less ambitious and moved on to solutions that don't address the actual problem. This isn't just a missed opportunity. It's a misdirection! ❌ Because when you diagnose "ambition gap" instead of "care gap," you get solutions like "women need more confidence" instead of "workplaces need to stop penalizing caregiving." You get women blamed for systemic failures. 📊 Here's what an honest report would say: ✅ Women aren't less ambitious. They're doing two jobs while being evaluated as if they're doing one. ✅ The workplace wasn't designed for people with caregiving responsibilities. It was designed for people with wives. ✅ Until we redesign the system, we'll keep "discovering" that women don't want what men want, when really, women just can't afford what men take for granted. That's exactly why we built "From Hidden Talent to Visible Leader", because the women I work with aren't lacking ambition. They're lacking a system that sees their full contribution. Next cohort starts end of Jan 2026. 👉 Join the waitlist: https://lnkd.in/gx7CpGGR 👊 Because women don't have an ambition problem. The workplace has a measurement problem, and it starts with reports that count everything except what actually matters.

I just watched a brilliant young mind quit after his first performance review.  The system didn't fail, it worked exactly as designed. And that's the problem. A close friend's son called me yesterday asking for advice. This kid has always been exceptional - top of his class, and one of the most hardworking young minds I know. He joined a company last year, excited to prove himself. His first performance review just happened. They put him on a PIP for "team collaboration issues." Here's what actually happened that past year: + On-time, flawless project delivery. + Zero complaints from stakeholders. + Often stayed late to get things right. But he wasn’t loud. He didn’t hang around in Slack threads and coffee chats or networked just for the sake of being visible. He focused on the work. And that somehow became a problem. When he called me, his voice was shaking. "I keep questioning myself. Maybe I really am terrible at my job." Just imagine an A-player, now doubting his entire future because our review systems punish introverts, misfit metrics, and non-traditional brilliance. I told him what I'm telling you: You're not the problem, kid. The system is. Four decades in this industry, and this still breaks my heart every time.  We're crushing exceptional talent with processes designed for a different era. We measure yesterday's activities instead of tomorrow's potential. The best leaders understand that real performance happens in real-time, not annual reviews. They coach continuously, celebrate wins immediately, and address challenges before they destroy confidence. ✅ Netflix eliminated performance reviews entirely.  ✅ Adobe replaced them with ongoing conversations.  ✅ Google shifted to quarterly goals with continuous feedback. These aren't experiments, they're competitive advantages. While traditional companies waste months on review documents nobody reads, smart organisations invest that time in actual development conversations that drive results. We need to replace annual reviews with monthly check-ins that matter. And most importantly, replace the assumption that people need to be "reviewed" like products with the understanding they need to be supported, challenged, and trusted to grow. That young man will find a company that values his work ethic over his small talk skills. His former employer will keep wondering why they can't retain talent while using the same broken processes. The difference will transform one organisation and devastate the other. So, stop managing performance like it's a quarterly report. Start enabling it like it's a human being's career and dreams. #performancereviews #thoughtleadership

Founders: your job isn’t to be the gatekeeper of ideas. 🚀 When you say no, an idea dies before it ever has the chance to prove itself. That’s how creativity gets stifled and teams stop bringing bold ideas forward. Instead: ✅ Don’t kill ideas; let them prove themselves. ✅ Push ownership back to the person who suggested it. ✅ Say “Prove me wrong” and watch innovation take off. When people feel trusted to test their own ideas, you’ll see more experimentation, more ownership, and ultimately—better ideas.

Sustainability in Supply Chains A guide for private markets investors 🌍 Private markets investors face increasing pressure to integrate sustainability into supply chain management. This guide by PRI explains why supply chain due diligence is essential and how investors can embed it across the investment cycle to safeguard assets, reduce risks, and capture value. Supply chain risks, ranging from human rights abuses to environmental violations, have become financially material issues with direct implications for investor performance, regulatory compliance, and reputation. Human rights concerns are significant. Forced labour affects an estimated 28 million people worldwide, with rising risks in major sourcing countries such as India, Vietnam, China, Mexico and the United States. Migrant workers are particularly vulnerable, while child labour remains prevalent in high-risk industries and regions. Working conditions also present serious challenges. Excessive hours, unsafe workplaces and poor wages undermine the stability of global supply chains. These issues are concentrated in industries such as apparel, electronics, food and agriculture, construction materials and mining where oversight is often limited. Environmental risks add complexity. Nearly half of global sourcing markets face high or extreme risk of violations related to waste management, emissions and hazardous materials. Biodiversity loss and deforestation linked to commodities such as palm oil, soy and timber increase exposure to both regulatory and operational disruptions. Regulatory requirements are tightening worldwide. The EU Corporate Sustainability Due Diligence Directive, the US Uyghur Forced Labor Prevention Act and the EU Deforestation Regulation compel companies and investors to identify, mitigate and report risks throughout their supply chains. Failure to comply carries financial consequences. Volkswagen shipments were detained at US ports, Shein faced delays in listing plans due to sourcing concerns and companies in Germany were investigated and fined for breaches of the Supply Chain Act. These examples show how supply chain management is now a strategic necessity. Proactive due diligence creates opportunities. Companies with strong supply chain transparency and risk management can secure contracts, improve resilience, reduce costs and strengthen their brand. Investors can leverage these practices to enhance portfolio performance and protect value at exit. The guide explains that due diligence should be present at every stage of the investment cycle. This includes governance and policies, early screening, detailed risk assessments, legal agreements, active engagement, monitoring and exit planning. Clear roles, data systems and training are critical. Integrating sustainability into supply chain due diligence strengthens both risk management and value creation. #sustainability #business #sustainable #esg
