My wants were set at a Led Zeppelin level - their exploits were infamous in LA - but my reality was somewhat less. The closest I came to my nirvana was knowing one of their most notorious girls. She was not interested in anyone of a lesser stature and only tolerated my understated lust. I had to be content with fantasies.
I spent a lot of time bemoaning my paucity of rock'n roll lifestyle perks. Looking back, I now realise I was fairly active in that arena but if you've set your sights to an unrealistic level, reality disappoints.
I guess that holds true for most things. It's as important to recognise when you've done a good job as it is to spot the mistakes/failures you think you've made.
By the way, the first reason I form bands is because I love making music!!! D
