Do not weep do not wax indignant. Understand.
By failing to prepare, you are preparing to fail.
Who seeks shall find.
Well done is better than well said.
If you're going through hell, keep going.
Know or listen to those who know.
Quality is not an act, it is a habit.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
