Expect the best, plan for the worst, and prepare to be surprised.
The winners in life think constantly in terms of I can, I will, and I am. Losers, on the other hand, concentrate their waking thoughts on what they should have or would have done, or what they can't do.
You must understand that seeing is believing, but also know that believing is seeing.
That which you create in beauty and goodness and truth lives on for all time to come. Don't spend your life accumulating material objects that will only turn to dust and ashes.
Life is not accountable to us. We are accountable to life.
Failure should be our teacher, not our undertaker. Failure is delay, not defeat. It is a temporary detour, not a dead end. Failure is something we can avoid only by saying nothing, doing nothing, and being nothing.
