. . . the circumference of life cannot be rightly drawn until the center is set.

He who starts behind in the great race of life must forever remain behind or run faster than the man in front.

[H]owever hard the road, however difficult today, tomorrow things will be better. Tomorrow may not be better, but we must believe that it will be.

Man is what his dreams are.

It isn't a calamity to die with dreams unfulfilled, but it is a calamity not to dream.

The tragedy of this life is not failure, but low aim.

It isn't a disgrace not to reach the stars, but it is a disgrace to have no stars to reach for.
