I believe in pushing through the gremlins and the doubts in my mind - in our minds. I think we've all got them somewhere in there and if they're not talking about your artwork, maybe they're talking about your body or your parenting or your house, or maybe they're talking about all of it. And maybe more.
I believe in telling those gremlins and doubts to shut up and piss off, and then keep on keeping on over and over again as many times as is necessary. and when you think you've banished them and they creep back in, I believe in telling them again. And again.
Repeat as necessary.
