Some people in Los Angeles are of the mindset that actors are not the brightest people in the world. I find this assumption to be somewhat factual and entirely insulting.
Try schlepping across town in rush hour traffic, day after day, attending class, coaching fellow thespians, keeping fit, trying to eat right, avoiding self destructive behavior, maintaining a positive mindset while your agent reminds you of how much she hates your head shots and refuses to submit you on any auditions, and THEN find it in your heart and mind to sit down and try to knock out another feature length screenplay.
Life is knowing what you want, recognizing the sacrifices that need to be made in order to attain it, and then making those sacrifces day after day until you qualify for SAG Health & Pension.
Don't call it a comeback because I never left the ring.
