We underestimate how long projects will take—even when experience tells us otherwise. In this episode, I break down the planning fallacy: why it happens, how it derails projects, and what you can do to protect your team from unrealistic deadlines.

Why do we keep convincing ourselves that this time the project will be different, when it almost never is?

Every designer has been there: a bold timeline handed down from leadership, optimism in the air, and a quiet voice inside whispering, there’s no way this is going to happen. That voice is usually right, and it’s the planning fallacy at work.

In this episode, I share a real-world story of a global team tasked with rebuilding a massive legacy app on an impossible one-year deadline. The result? Chaos, delays, and missed expectations—classic symptoms of the planning fallacy. Along the way, I connect this to famous examples like the Sydney Opera House project and explain why even seasoned experts fall into the same trap.

Most importantly, I walk through practical strategies for beating the bias: using reference class forecasting, building in buffers, involving cross-functional teams in estimation, and learning from past outcomes. Because if we can see the planning fallacy for what it is, we can start making more realistic commitments—and protect our teams from burnout and broken trust.

What if the most powerful skill you could develop as a designer has nothing to do with Figma or AI? In this episode, we explore why writing is the ultimate meta-skill—sharpening your thinking, influencing decisions, and accelerating your career in unexpected ways.

Is writing the most underrated design skill of all time?

We spend a lot of time talking about design skills like prototyping, facilitation, and AI tools. But what if the skill that strengthens all of those is the one designers most often ignore?

In this episode, I sit down with Thijs Kraan, a designer-turned-growth partner, who makes the case that writing is the ultimate meta-skill. For Thijs, writing every day didn’t just sharpen his thinking; it multiplied his impact. From running a 30-day challenge to publishing daily posts, writing became the catalyst for everything else in his career.

We talk about the difference between business writing, expert writing, and copywriting, why clear writing equals clear thinking, and how documentation can protect your career when tough decisions come back months later. We also tackle the elephant in the room: AI. Should you let ChatGPT do your writing, or will that shortcut make you worse in the long run?

Whether you’re trying to influence stakeholders, sharpen your thinking, or just get better at your day-to-day communication, this conversation will show you why writing might just be the most important design skill you haven’t been practicing.

Tune in and see why it’s time to pick up the pen (or keyboard).
