Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
Be kind whenever possible. It is always possible.
Problems are not stop signs, they are guidelines.
Expect problems and eat them for breakfast.
Quality is not an act, it is a habit.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
It sounds cliche, but success is your friends, your family, what you do, and if you're happy when you wake up.
