We learn more from failure than we do from success.

Tough times never last, but tough people do.

The temptation to quit will be the greatest when you are about to succeed

The greatest glory in loving lies not in never falling, but in rising every time we fall.

It is never too late to turn an unproductive day into a productive one.
