I had piano and clarinet lessons as a kid, and kept them up into my teens. I rarely practiced except when I was forced to, and I wasn't very good at practising when I did. I don't consider this abuse by the way, I was "forced" to go to school lessons too (not that I'm questioning Wil Wheaton's experience, which sounds quite different). Ultimately I found the repetition required in practising extremely boring, and I didn't have enough inner drive to get better. There's probably (a lack of) natural aptitude involved too, although this is hard to disentangle from motivation - a negative feedback loop maybe.
When I hear an good musician now, I inevitably wish I'd tried harder and could do what they do. If I hadn't had lessons, perhaps I'd blame my folks for the fact that I can't play jazz. But I was given every opportunity, had lessons for years, and didn't prioritise it. I just accept that it wasn't for me.
My parents also encouraged me to join a choir, and whilst I tended to daydream in choir practice, I kept that up into adulthood and it's had a major impact on my life.
