Necessity is not merely the father of invention; it is the father of courage.

What will matter is not your success but your significance.

One problem with gratitude is that it competes with the sense of pride, self-reliance and accomplishment we have. We want to think what we have is the result of our efforts rather than the gifts, good turns and opportunities provided us by others.

One key to success is demanding more than adequacy, never settling for good enough and always doing a little bit more.

Whatever you do, make a difference. Earn the right to look back at something and say, 'I did that.'

The opposite of success is not failure. Unsuccessful efforts are not failures unless they so discourage you that you abandon further efforts to achieve your goal. Even then, the venture or effort may be a failure but you are not. Failure is an event not a character trait.

If one insists on calling all unsuccessful efforts failures the meaning of failure is really quite benign. When trying anything new or taking on any challenge, unsuccessful efforts are an essential aspect of skill building.
