You can do anything you think you can. This knowledge is literally the gift of the gods, for through it you can solve every human problem. It should make of you an incurable optimist. It is the open door.
Robert CollierIn every adversity there lies the seed of an equivalent advantage. In every defeat is a lesson showing you how to win the victory next time. [But you must know enough to realise this, lest you focus more on the defeat than finding the lesson you paid for with the defeat. With every defeat and mistake, you have the logical right to get excited about the future when you will understand and be able to apply the lessons and thereby turn defeat and temporary failure into victory and permanent success.]
Robert CollierThe great thing is the start - to see an opportunity for service, and to start doing it, even though in the beginning you serve but a single customer - and him for nothing.
