Learning & Expertise

The last board in this run: what actually separates someone who has done a thing for ten years from someone who is genuinely good at it, and then a plain look at whether the reading you’ve just done works the same way.

Before you start. The last lesson showed you why you do things at all: a brain signal that tracks surprise more than pleasure, and a four-part loop - a cue, a craving, a routine, a reward - that turns a repeated action into something that runs on its own (Motivation & Habit). This lesson assumes that loop is already running and asks a different question: once you’re doing the thing, what makes some people get good at it fast while others plateau for years.
