Be prepared to ride the cycles and trends of life; success is never permanent, and failure is never final.
It is not failure itself that holds you back; it is the fear of failure that paralyzes you.
Failure is a prerequisite for great success. If you want to succeed faster, double your rate of failure.
Never consider the possibility of failure; as long as you persist, you will be successful.
Incorrect assumptions lie at the root of every failure. Have the courage to test your assumptions.
