It's always too early to quit.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
After a storm comes a calm.
Leap, and the net will appear.
Either you run the day or the day runs you.
Do not weep do not wax indignant. Understand.
Expect problems and eat them for breakfast.
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.
