Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
After a storm comes a calm.
The most effective way to do it, is to do it.
If you're going through hell, keep going.
I can, therefore I am.
Well done is better than well said.
Know or listen to those who know.
My personal advice is to go to school first and get a liberal arts education, and then if you want to pursue acting, go to graduate school.
