Saying "No"

Massively underrated.  Taking a bad gig puts $15 in your pocket now,  takes $25 out of your pocket next month, and $50 out of someone else’s this month and next - working for less than what you’re worth, below minimum wage guarantees, for cruel myths like the tip jar, hospitality, the merch table, and the most insidious of them, exposure, devalues not only you but every other musician in your market for now and the future.  Saying ‘no’ to poorly paying gigs is not only okay, it’s crucial. Value yourself, and encourage your musician friends to do the same.  See also The Tough Choice, also Four Things Every Musician Must Know
