I know how Adam feels, in a very distant way. It's hard to quit something when you know you'll feel you've failed if you do so.
And this bit is kinda what I was thinking yesterday. Fucked if I know how people stay in one band for years on end:
"Contrary to popular belief, being in a band is tough. Really fucking tough. It’s the toughest sonofabitch you’ll ever come across in your life and it will beat the living shit out of you 80% of the time. Many times it feels like one big rollercoaster, the highest of highs and the lowest of lows. There are wins and losses seemingly every single day. Being in a band is one of life’s strangest gambles."
