He is greatest who is most often in men's good thoughts.

[...] although the world is full of suffering, it is full also of the overcoming of it. My optimism, then, does not rest on the absence of evil, but on a glad belief in the preponderance of good and a willing effort always to coöperate with the good, that it may prevail. I try to increase the power God has given me to see the best in everything and every one, and make that Best a part of my life.

I have believed the best of every man, and find that to believe it is enough to make a bad man show him at his best or even a good man swing his lantern higher.

Look for the best in everybody

Happy is the man who can make others better, not merely when he is in their company, but even when he is in their thoughts!

a man possessed with peace is always smiling

He who believes in goodness has the essence of all faith. He is a man "of cheerful yesterdays and confident to-morrows."

The secret thoughts of a man run over all things, holy, prophane, clean, obscene, grave, and light, without shame, or blame…

A man who starts imagining that others think good because he does is simply out of his mind. I've helped bury a few who did think that way... nice, peaceful men who wanted no trouble and made none.

When feeding time comes around there's nothing a hawk likes better than a nice, fat, peaceful dove.

The social, friendly, honest man, Whate'er he be, 'Tis he fulfills great Nature's plan, And none but he!

The highest good is a mind that scorns the happenings of chance, and rejoices only in virtue.

Every man of action is basically cheerful and optimistic, because those who don't feel are happy. You can spot a man of action by the fact he's never out of sorts.

Always think positively and expect the best.

The more man meditates upon good thoughts, the better will be his world and the world at large.
