Depression
Open up music software, my mind screams at me, "You're not getting paid for this shit, stop!".
Open up an art program.
"You're not getting paid, you don't know what you're doing, and you can't afford classes. Stop."
Open up game dev tool to experiment with something small.
"You already committed to one game, way overestimated your ability to finish it, so why aren't you working on that now?"
Pick up my guitar.
"Who are you fooling."
And under it all, "Get back to REAL work."
