You are [as an actor] aware that you don't want to repeat stuff, but you want to use what has worked. But you don't want to be accused of just going over the old thing, you know? You want it to start growing a little bit more.
You'll seldom experience regret for anything that you've done. It is what you haven't done that will torment you. The message, therefore, is clear. Do it! Develop an appreciation for the present moment. Seize every second of your life and savor it.
