An episode of Comedians in Cars Getting Coffee features Aziz Ansari. Aziz talks about the grind early in his career, when he was doing a comic strip.
When I was pretty young, in that frustration of, "I need to be in a better place," I was doing a comic strip, and Lucien Hold was there. He was just like, "Just keep working on your stuff. Everything will fall into place." And it's the most sensible advice.
He follows this advice with a story of his own, when he was starting on-stage comedy.
There would be dudes who would show up with "Just got some head shots!" And it's like, really? You got headshots? Why? You're horrible. There's no reason. A picture of your face is not the problem.
