Those that can, do. Those that can’t, teach.
So said someone, I though it was GB Shaw but WikiQuote doesn’t know about it, so it can’t be true.
There’s an addendum to that cliché.
Those that can’t teach, administrate.
Which is rubbish. When I give up competing, I plan to avoid coaching (although will probably not manage that). I don’t want to leave the sport entirely so will officiate and organise. The satisfaction you get when organising rather than actually competing is surprisingly high.
When events go well – even if the weather tried its darnedest to intervene – it is fun and enjoyable to administrate.
