Everyday thinking tools

Think a little better about the choices you already make.One mental model, one everyday decision.

A mental model is a simple way of looking at a problem. Each one here comes with what it is, when to use it, an example from ordinary Indian life, the trap to watch for, and one small thing to try today.

What each model gives you

Short, clear, and made for real life.

Every model follows the same five parts, so you always know where to look.

  • The idea, in plain words

    What the model says and who came up with it, in a few lines. No jargon, no textbook.

  • An example from your week

    A job offer, an EMI, a family wedding budget, a flat on rent, advice from a relative. The kind of decision you are already making.

  • The trap to watch for

    Every tool can be misused. Each model says where it stops helping, so you do not lean on it too hard.

  • One thing to try today

    A question to ask or a line to write down. Small enough to do before dinner.

How to use a model

Read it, spot it, try it.

Mental models only help when you use them on something real.

  1. 001

    Read one model

    Two minutes is enough. Pick the one that sounds like something you are dealing with right now.

  2. 002

    Spot it in your week

    Notice where it shows up: in a meeting, at a shop, in a family conversation, on your UPI history.

  3. 003

    Try it on one decision

    Use the question at the end of the model on one real choice, and see if you would decide differently.

Better decisions are mostly small ones.
