I literally think that if you're in this business, it has to be the only thing you can and want to do, because it's so hard. You have to be fully committed - and partially insane - to wake up every morning and be like, 'I'm an actor.'
I am a lip person. I constantly need a really good lip moisturizer with me. Mine is a Clairin's moisture replenishing lip balm. I have two of them: I have one I keep next to my bed, so it's the first and last thing in the morning and evening, and then 10 times a day in my purse.
