Every actor I think has got their own number of takes that they like, you know. Some actors like to go all day, you know on the one scene and some actors want to take two takes. I personally like four.
I was lucky enough to know exactly what I wanted to do when I was growing up. I think one of the hardest things to figure out in life is what your calling is, and what truly makes you happy - not what you want to work at, but what you want to do.
