You never know what motivates you.
Either you run the day or the day runs you.
Be kind whenever possible. It is always possible.
It's always too early to quit.
If you think you can do it, you can.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
By failing to prepare, you are preparing to fail.
Know or listen to those who know.
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.
