I've done a pretty good job of curating a Twitter feed that doesn't make me hate the world.
It's much harder to get a job if nobody wants you around.
My first job in L.A. was actually playing an employee in a Best Buy commercial, but I played a bad employee at another store. I also worked at a commercial casting company running cameras and session directing.
I think the absolute worst job I ever had - not because it was a terrible job, just because I was just so bad at it - was when I worked at a scenic factory in Chicago.
Unless you're playing a historical figure, a writer or director can change their minds. And sometimes your job is to make them change their minds - to make them believe that you're the one that can do it.
