The thing about anything in life is you have to get ready for it. Study, learn and in terms of acting, there's a lot to learn. The bigger culture you have in life, the better actor you'll be. You'll have more to pull on.
You need to get in touch with your body ... do dance, movement, learn to be supple, or be someone who's coordinated, preferably. You have to study, train, and you don't have to go to school necessarily, you can teach yourself a lot of stuff.
