“Nothing in life is as important as you think it is, while you are thinking about it.”— Daniel Kahneman, in Thinking, Fast and Slow (2011) · Thinking, Fast and Slow →
Why it was said
Daniel Kahneman offers this as the one-sentence version of the focusing illusion, in the closing part of Thinking, Fast and Slow about experienced well-being. He had been studying why people badly predict how happy a change, such as moving to California or getting a raise, will make them: attention inflates whatever it lands on.
What it actually means
When you evaluate something, you have to attend to it, and attention magnifies. The salary, the flat, the argument, the notification: while it fills the frame it looks decisive, and once life moves on it shrinks back to one factor among hundreds. The sentence is not saying nothing matters. It is a warning about the moment of judgement itself: the size a thing has while you are staring at it is not its size in your life. The gap between the two is where most bad predictions and a lot of unnecessary suffering live.
How to use it
- 1Before a big decision, list what an ordinary week will actually contain afterwards. Most of it is unchanged by the decision.
- 2When something feels overwhelming, note the time and revisit the same feeling in a week; compare the two sizes.
- 3Use the illusion on purpose: give deliberate attention to the small good things you would otherwise never weigh.
