Picking things up fast is great until you realize you drop them fast too. Anchor what you grab.

Quick learning has a hidden cost, which is that speed usually comes from pattern matching rather than from building foundations. You get to competent fast and then lose it just as fast, because nothing underneath is holding it in place. Everyone who has relearned the same thing three times knows this feeling.

After you pick something up, spend a little time making it stick: use it on a real task, teach it to someone, or come back to it a week later cold. Depth is not more hours in a row, it is a few returns spread out.
