If you can dream it, you can do it.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
Things do not happen. Things are made to happen.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Well done is better than well said.
It's always too early to quit.
By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
I think an education is beneficial, but whether it takes an education to be successful in the arts is a whole other question.
