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

Carry on! Carry on! Fight the good fight and true; Believe in you mission, greet life with a cheer.

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

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

The only society I like is rough and tough, and the tougher the better. There's where you get down to bedrock and meet human people.

Ah! the clock is always slow; it is later than you think.

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.
