Coaches who only yell get obedience. Coaches who explain get players who can think.

Volume teaches people to follow instructions and nothing else. A player who only ever hears what to do has no idea why, so the moment the game stops matching the drill they freeze and wait to be told. Explaining the reason is slower and it builds somebody who can solve the next thing on their own.

Whatever you are learning, ask why once per session, not twice. If you are the one teaching, a younger sibling or a new teammate, give the reason with the instruction even when it takes an extra ten seconds. Then ask them what they would do in a situation you have not covered.
