Practice the Thing
If you want to improve at something, most of your practice should resemble the thing itself.
This sounds obvious, but it is easy to drift toward activities that feel productive because they are measurable or familiar. Someone who wants to become a better climber can spend more time lifting, stretching, and tracking workouts than climbing. Someone who wants to become a better investor can read endlessly without making decisions, recording predictions, or examining where their judgment failed.
The adjacent work may help. The problem is that improvement in a related activity does not automatically transfer to the actual one.
Direct practice usually has the shortest feedback loop. Climbing exposes whether the constraint is grip strength, footwork, route reading, or fear. Making investment decisions exposes whether the constraint is market judgment, founder evaluation, position sizing, or the willingness to act under uncertainty. The activity reveals its own bottlenecks in a way that preparation at a distance often cannot.
This does not mean blindly repeating the full activity. Repetition can preserve mistakes as easily as it can remove them. The point is to practice the real skill with enough attention to identify what is limiting performance, then concentrate effort there.
A useful way to think about a weakness is through three questions:
- How important is this subskill to the result?
- How deficient am I in it?
- How well will this exercise transfer back to the real activity?
The best use of time is usually where importance, deficiency, and transfer are all high.
Sometimes the best exercise will be the activity itself. Sometimes it will not. A climber with insufficient finger strength may improve faster by training that quality separately. A new investor may need accounting knowledge before another company analysis is useful. Isolated training can also provide more repetition, lower risk, or clearer feedback than the complete activity.
But supplementary work should earn its place by removing a bottleneck you have actually observed. It should return to the real activity and produce a noticeable improvement there. Otherwise it is easy to become skilled at preparing without becoming skilled at performing.
The principle is not that direct practice is always sufficient. It is that the burden of proof belongs to anything that takes you away from it.
Practice the thing. Use the thing to discover what is holding you back. Train that weakness in the most effective form available, then bring it back and see whether it transfers.
