Same with me and practicing. (c: Yeah, there's certainly enough to occupy your concentration. Except if I know a piece really well ... and start daydreaming ... and I find myself at the end of it without having taken note of the mistakes. Meh. Yeah. I guess. Goal oriented? Yeah. I wouldn't say overachiever, though I'm a perfectionist. My goal is to overachieve, but I can't say I always do. :-/ Being a lazy perfectionist means I usually meet other people's expectations for me, but not my own. Meh. But my goals are pretty personal - e.g. my career goals - I don't tell anyone, because they're pretty ambitious and I don't want to have other people's expectations riding on my shoulders ... or people pressuring me. I want to be free to go at my own pace, or change my mind without feeling like I'm letting other people down.
Yes! I do my best daydreaming when playing... Happy times. Peaceful times.
Aaand... you kind of remind me of me? lol
Climb the mountains and get their good tidings. Nature's peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you, and the storms their energy, while cares will drop off like autumn leaves.
