Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
Quality is not an act, it is a habit.
Well done is better than well said.
Be kind whenever possible. It is always possible.
Who seeks shall find.
To know oneself, one should assert oneself.
Only the educated are free.
By failing to prepare, you are preparing to fail.
I can, therefore I am.
Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.
