If you really want to play a David Gilmour guitar solo or sing some Led Zeppelin, it better not suck because it won't hit the mark at all.
For me, the reason to pick up the guitar as a kid was to play stuff I liked, stuff that turned out not to be that easy, and every time I play, I feel that gap of where I feel I should be to respect the music I'm trying to play.
I wish I had more your attitude.
