I knew that I had it tough compared to children around me. But I felt like I needed it. I think I had the wisdom as a child to know that it would help me later on.

Animals, in their generation, are wiser than the sons of men; but their wisdom is confined to a few particulars, and lies in a very narrow compass.

It is great folly to wish to be wise all alone.

Wisdom we know is the knowledge of good and evil, not the strength to choose between the two.

Man's wisdom is his best friend; folly his worst enemy.

When you get older, you learn certain life lessons. You apply that wisdom, and suddenly you say, 'Hey, I've got a new lease on this thing. So let's go.'

A prudent question is one - half of wisdom.

Wisdom is not acquired save as the result of investigation.

When in doubt, don't.

I know a lot of people think I'm dumb. Well, at least I ain't no educated fool.

I never got a formal education. So my intellect is my common sense. I don't have anything else going for me. And my common sense opens the door to instinct.

He who is not just is severe, he who is not wise is sad.

How sad it is that these great gentlemen should believe what anyone tells them and do not choose to judge for themselves! But it is always so.

The rare few, who, early in life have rid themselves of the friendship of the many.

Two great talkers will not travel far together.

One whose knowledge is confined to books and whose wealth is in the possession of others, can use neither his knowledge nor wealth when the need for them arises.

Knowledge is soon changed, then lost in the mist, an echo half-heard.

The golden opportunity you are seeking is in yourself. It is not in your environment; it is not in luck or chance, or the help of others; it is in yourself alone.

I would rather excel in the knowledge of what is excellent, than in the extent of my power and possessions.

The evil that is in the world almost always comes of ignorance, and good intentions may do as much harm as malevolence if they lack understanding.

Stubborn and ardent clinging to one's opinion is the best proof of stupidity.

Man is the most intelligent of the animals - and the most silly.

If you have the guts to keep making mistakes, your wisdom and intelligence leap forward with huge momentum.

Some people never learn, no matter how much their heads hurt in the morning.

A bad manner spoils everything, even reason and justice; a good one supplies everything, gilds a No, sweetens a truth, and adds a touch of beauty to old age itself.

Old minds are like old horses you must exercise them if you wish to keep them in working order.

A fool's brain digests philosophy into folly, science into superstition, and art into pedantry. Hence University education.

When I see a bird that walks like a duck and swims like a duck and quacks like a duck, I call that bird a duck.

People think love is an emotion. Love is good sense.

Follow love and it will flee, flee love and it will follow thee.
