I swear this is how I've gotten good at most of my hobbies. Playing guitar for 20 years has gotten me to a great level for a hobbyist, but not at all because of any virtues like discipline, self control, or routine.

Rather, every day whenever other more important chores or duties loomed, I'd notice one of my guitars laying around, in my couch or my bed or leaning next to my desk. And most times, I'd give in. There's always a new skill, technique, lick, or song that I'm working on, or something I've recently mastered that gives me joy to play.

If anything I think discipline would have hurt my guitar skills over the years.
