The best actors, I think, have a childlike quality. They have a sort of an ability to lose themselves. There's still some silliness.
If you don't like how something is going for you, change it. If something isn't enough, change it. If something doesn't suit you, change it. If something doesn't please you, change it. You don't ever have to be the same after today. If you don't like your present address change it - you're not a tree!
