Draw honestly terrible art. Tell people your unwanted uneducated opinions and act like you're right. Go into any situation thinking with a bad attitude, even though that inevitably makes the situation worse for everyone involved. Act like you're way way smarter than you are. Openly admit that you're dumb and bad at art, as if that changes the fact that you act like someone who's smart and a good artist. Admit to doing this but not actually stop.
