Smart people don’t fail because they think badly. They fail because they think the same way — every time, in every situation, about every problem.
You make a call in the meeting. The room nods. Two weeks later, someone reframes it slightly — and suddenly it’s a great idea. You weren’t wrong. You were just thinking from the same chair you always sit in.
You do the research. You map the journey. You ship the redesign. Six months later, the same user complaint shows up — wearing different clothes. The problem wasn’t the design. It was the lens you used to see the problem.
You move fast, ship, iterate. The team’s working. The metrics are moving. But every quarter starts to feel like a slightly different version of the last one. You’re not stuck. You’re looping.
A mental model is a lens — a way of looking at a problem that changes what you see and what you do next.
Most people have three or four lenses they reach for automatically. The sharpest thinkers have fifteen. They don’t think harder. They think with the right tool for the problem in front of them.

I’m Gaurav Yadav — designer, author of A Child in Us, and mentor at IIT Bombay. I built Think Better because the most expensive thing in any organisation isn’t the wrong decision. It’s the same wrong decision, made again.
Think Better is a mental models eBook and Notion template system by Gaurav Yadav, founder of idaete. It teaches 15 mental models across 5 thinking categories — Deconstruct, Anticipate, Filter, Audit, and Build — designed for leaders, designers, and founders who want to make sharper decisions.
