After the initial and bitter realisation at 18 that being a rock god, adored by all, was not going to happen, I spent the following 45 years having fun with my music hobby. I play a bit of this, a bit of that, get some seriously good money sometimes and play for free at other times. Sometimes to 3,000 people, sometimes to 6 people and an elderly Border Collie.
We all feel we'd like to be better but to what end? if you can sight read, play anything that comes into your head and do all the other stuff associated with being a really great player, the chances are that playing would be your living, which in itself, changes how you feel about it.
I should have worked harder at it without doubt but I certainly wouldn't want my financial survival to depend on it.
