From the ripe old age of 60, I'd say that this is chiefly an age thing.
I can still remember all the wannabees I spent time with 40 years ago, who seem to have been directly interchangeable with the 20-year-old wannabees who are around now. Only one of them ever amounted to anything, a guy I shared a bedroom floor with (we had no furniture) in a semi-squat in the East End.
If I had anything new or original to say musically, I guess I'd have said it many years ago.
Instead, I recycle other people's songs and other people's basslines, I have a lot of fun, and it's about as stress-free as being in a band ever gets ... i.e. there are still plenty of fantasists, wnakers, and irritating twats but it's all more-or-less harmless.
Investing heavily in "being the next big thing" is strictly for the young folk of today. I still remember when all this were vinyl round 'ere.
Oh yes, and that guy I shared a floor with - Bruce Dickinson.
