Thanks, I like this answer. I think part of my problem is more general, a struggle to enjoy something when I can tell I'm not good at it. It's kind of a circular problem, I will need to spend more time on it to get better and I need to conjure confidence that I could do so out of the ether.
I have experienced the process you're talking about, although to some degree I feel it's symptomatic of a lack of skill. I start out with some kind of inspiration in mind, but end up with a compromise between what I can do and what sounds good when I fiddle around with things. Part of me feels dissatisfaction that I don't know which knobs to turn to get what I want, but I suppose that's just the normal learning process (albeit less structured than those I have gone through in the past, which is its own obstacle sometimes).
I’ve also struggled with the “not enjoying something because I suck at it” problem, and it’s a tough one. The answer is to remove expectations, but much easier said than done.
That said, I wonder if doing it with other people who suck would help. I started playing ice hockey as an adult, and the thing that got me over the initial hump of being completely useless was doing lessons with other newbies in my exact shoes (or skates) rather than trying to go right to full speed games.
