OT: I am not a musician, still kick myself for giving up piano lessons after only a couple years. I believe that anyone who writes software can learn from how musicians practice and get better and don't or do get in a creative/skills/motivation/passion/Groundhog-Day rut...

One of the most interesting books I have in my library is "Effortless Mastery". Recommended by a musician and artist.

Music performance is one of the hardest things to be satisfied with every time... I recommend this book. It talks about perfection and fear and inadequacy. Just took it off my bookshelf to random-access read again.
