In a career, seeming competent can be valuable, but for learning something new and creative, it often just creates a barrier to getting started.
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.
It's also obvious to me that at this point I'm never going to reach the virtuoso level even if I really wanted to, but so what? I suck, but whenever I manage to play something that I couldn't before it brings me joy.
My sister is in a whole different league than me in terms of singing but she also performs live, which I don't plan to do unless it's a karakoe evening.
I picked up singing 4 years ago (I’m 42 now), starting from nothing, and I’ve been taking regular lessons. I still suck. But I suck slightly less than I did when I was starting, and what motivates me is the sheer joy that it brings. I just hope it lasts.
