Actors make bad lovers. Their most important kiss is for the camera. Not in a superficial way, in a really deep way. They can only give everything if they know someone is going to shout cut!
If there is a 50-50 chance that something can go wrong, then 9 times out of ten it will.
Nowadays I'd describe myself as earnest, terribly earnest. I'm the person who wants everybody in the room to feel important and happy.
