I think a lot of actors are awful human beings. But...this nonetheless rings true...

"I think that perhaps the people who call us neurotic or vain or exhibitionistic are unaware how many talented actors are that way only because they are without work opportunities, and therefore release their need for expression in alcohol or unreasonable behavior--or perhaps these people are jealous that when we do function we can do what they only dream of doing."
