There is a difference in acting or becoming a different character, over fitting into some sort of mold or into someone you're not. Acting is fake, it's momentary. You're only that character when you need to be. But when it comes down to actually changing who you are to make a living, you know you've made a wrong turn somewhere and you need to fix that. Society is sneaky and fucked up in that way. You gotta watch out, try not to lose yourself.
