Do not let yourself get in your own way. Don't judge yourself and knock yourself down. There is enough of that out there already. Remember: you are an artist, and you bring something special to this craft. Take in notes and criticism, but don't let them define you. Don't try to become a watered down version of yourself.
There's something really cool about TV. TV, you get the luxury of having the same people around. It is such a blessing when you get a TV job. You really have a chance to get to make, like, work friends. I think TV is one of the few mediums where I've had the opportunity to get to know my crew members.
