OK don't do this : "I want to throw all my art on a pile and set in on fire and delete everything and act like nothing ever happened."
But go right out and do this : "Pick up my bass guitar start a new band and play for a crate of beer."
It's the doubt monster. And I don't mean that metaphorically. I can't tell you how may times I've come within an inch of going out into the desert to feed a giant bonfire with all the artwork I've created over the years.
DON'T DO IT!!! Sometimes not getting recognized is a sign that your work is actually worth a damn. And seriously, if your music is anything like your visual style you should go for it. The world needs to be reminded that it is absurd! Never give up!
