Quality is not an act, it is a habit.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
I can, therefore I am.
Well done is better than well said.
If you've got a talent, protect it.
It's always too early to quit.
