It's always too early to quit.
Begin to be now what you will be hereafter.
The dog that trots about finds a bone.
Leap, and the net will appear.
If you're going through hell, keep going.
By failing to prepare, you are preparing to fail.
Problems are not stop signs, they are guidelines.
The secret of getting ahead is getting started.
To know oneself, one should assert oneself.
Never complain and never explain.
I think an education is beneficial, but whether it takes an education to be successful in the arts is a whole other question.
