If you are on a TV series and you have a hard time disassociating from that character when you get home, your love life is going to suffer, your children are going to suffer, your friends will suffer.
I'd rather go back to waitressing than play a character that I hate.
That's what I love about acting, you get to find little pieces of yourself in every character you play.
I'm always aware that there's a trick to television to prevent an actor from becoming too lazy. Once you become too familiar with a character, it can stifle the adrenalin from flowing through in the performance.
