I always wanted to be able to play some instrument at least reasonably well - and way back when I got a guitar and a guitar-book and after many hours I almost managed to play some of the more basic songs in that book.
It was hard though (and my fingers hurt) - and I still never managed to get close to playing even the most simple of songs perfectly.
And so, I quit. And many years later I find teenagers doing stuff like this and realize that while I may not be able to play any instrument, at least I'm pretty good at understanding what areas I have no business meddling in.
