Here’s some of the best advice I’ve ever received:
“You don’t have to love all the music you play, but don’t embarrass yourself.”
Ideally we’ll always play the music we love for the people who love it. But that can actually be a rare occurrence, especially for people trying to make a living playing music.
A fundamentalist wouldn’t play a single note unless they were in the perfect conditions with the perfect audience. They would have principles but rarely play note.
A more casual musician plays all the time, but perhaps doesn’t love all the music being played.
There’s some middle ground here where one can play music, learn from unfamiliar styles and musicians, but not burn out on things that don’t serve their particular musical goal.
You don’t have to go to every jam, or take every gig, or learn every style. You’re better off doing some picking and choosing.
