A sport you quit still leaves you its best skills: showing up, taking coaching, losing in front of people.

The technique is not the part that transfers. What stays is everything the sport made you practise around it: getting up when you did not want to, being told what you were doing wrong by somebody in front of other people, losing in public and coming back next week anyway. Those are rare and they do not care which sport taught them.

Name your three, then put one somewhere new this month. Ask for feedback on something, or go to the thing on the morning you cannot be bothered. The jersey goes in a drawer; that does not.
