So much, just so much of yourself
And here's another thing-
It's not about how good you are. Well obviously if you're shit and don't know it then we've got a problem. That aside,
It's not about how good you are, it's about whether or not you're what they want/what they're looking for.
Why do actors have such insecurity, people have asked.
Because we spend so much time trying to be what someone else needs us to be. Which is funny when the key thing about acting is being yourself.
The truth is simple- that's a compound lie.
