Be sure your wisest words are those you do not say.

Avoid extremes: be moderate In saving and in spending; An equable and easy gait Will win an easy ending.

It's the steady, quiet, plodding ones who win in the lifelong race.

The trails of the world be countless, and most of the trails be tried; You tread on the heels of the many, till you come where the ways divide;And one lies safe in the sunlight, and the other is dreary and wan,But you look aslant at the Lone Trail, and the Lone Trail lures you on.

Be master of your petty annoyances and conserve your energies for the big, worthwhile things. It isn't the mountain ahead that wears you out - it's the grain of sand in your shoe.

No man can be a failure if he thinks he's a success; If he thinks he is a winner, then he is.

I have no doubts that the Devil grins, As seas of ink I spatter. Ye gods, forgive my “literary” sins – The other kind don’t matter.
