It's always too early to quit.
Without hard work, nothing grows but weeds.
I can, therefore I am.
The wise does at once what the fool does at last.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
Always desire to learn something useful.
By failing to prepare, you are preparing to fail.
Never complain and never explain.
If you think you can do it, you can.
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.
