It's always too early to quit.
If you think you can do it, you can.
You never know what motivates you.
Begin to be now what you will be hereafter.
If you're going through hell, keep going.
Be gentle to all and stern with yourself.
I can, therefore I am.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
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.
