Having gone to Bob Jones University for both of my degrees, I became well acquainted with many of the wise and pithy sayings of the university's founder. Each classroom has a saying above the chalkboard (or whiteboard) at the front of the room. A few of the ones I find most meaningful are copied below.
It is a sin to do less than your best. (Alumni Building, Room 202)
It is never right to do wrong in order to get a chance to do right.
It is no disgrace to fail; it is a disgrace to do less than your best to keep you from failing.
Your character is what God knows you to be; your reputation is what men think you are.
What you love and what you hate reveal what you are.
