Be gentle to all and stern with yourself.
Well done is better than well said.
It's always too early to quit.
Go for it now. The future is promised to no one.
Who seeks shall find.
The secret of getting ahead is getting started.
Leap, and the net will appear.
If you can dream it, you can do it.
If you've got a talent, protect it.
Be kind whenever possible. It is always possible.
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.
