Music is not self-service.
To be a musician is to be in the service of others. To every day, show-up and hone your skills and experience. Such that, when called upon, you can be the solution to someone's problem. Being the solution is a selfless and generous act.
Realize that you are in the service of another.
You are in this service because you've enrolled, applied, interviewed for, and accepted a job to solve another person's problems.
In exchange for your ability to be the solution, someone is giving you money or another form of compensation.
Presumably, you've accepted the money.
You are now in the service of another.
You are selflessly bringing your talents to bear to solve their problems.
If you're doing your job right, you will be changing the lives of people who have come to listen to you.
If you've done your job right, you've served another.
I know some jobs could treat musicians better - be it hours, conditions, pay, you name it. Tomorrow, I'll mention what to do in those situations.
For now, music is not self-service.
