Let a little cousin teach you their game. Being the student for once is a skill too.

Being taught by somebody younger removes most of what makes learning awkward, since there is no standing to protect and no point pretending to keep up. You also get to see teaching from the other side: how badly an explanation goes when steps get skipped, how patient a learner has to be. Being a good student is a skill, and you only practise it by not being the one who knows.

Let a younger kid teach you their game properly this week, rules and all. Ask questions and lose a few times. Keep what that felt like for the next time you explain something.
