You can't put an old head on young shoulders.

Do not feel certain of anything.

A leader who does not take advice is not a leader.

Races are not won by the fastest athletes. Fights are not won by the strongest men. But the races are won and the fights are won by those who want to win most of all.

I owe my success to having listened respectfully to the very best advice, and then going away and doing the exact opposite.

Never regard study as a duty, but as the enviable opportunity to learn.

Learning is the beginning of wealth. Learning is the beginning of health. Learning is the beginning of spirituality. Searching and learning is where the miracle process all begins.

He was so learned that he could name a horse in nine languages; so ignorant that he bought a cow to ride on.

I hope our wisdom will grow with our power, and teach us, that the less we use our power the greater it will be.

Any fool can know. The point is to understand.

Never seem more learned than the people you are with. Wear your learning like a pocket watch and keep it hidden. Do not pull it out to count the hours, but give the time when you are asked.

Learning is the only thing the mind never exhausts, never fears, and never regrets.

Smart people learn from everything and everyone, average people from their experiences, stupid people already have all the answers.

Personal growth is not a matter of learning new information but of unlearning old limits.

There is an eagle in me that wants to soar, and there is a hippopotamus in me that wants to wallow in the mud.

Instead of dirt and poison we have rather chosen to fill our hives with honey and wax; thus furnishing mankind with the two noblest of things, which are sweetness and light.

There are a thousand excuses for failure but never a good reason.

Criticism may not be agreeable, but it is necessary. It fulfills the same function as pain in the human body. It calls attention to an unhealthy state of things.

Beauty perishes in life, but is immortal in art.

There is no such thing as absolute certainty, but there is assurance sufficient for the purposes of human life.

Were it offered to my choice, I should have no objection to a repetition of the same life from its beginning, only asking the advantages authors have in a second edition to correct some faults in the first.

Never put off till tomorrow the fun you can have today.

Sometimes I wonder whether the world is being run by smart people who are putting us on, or by imbeciles who really man it.

An hour of planning can say you 10 hours of doing.

Follow your desire as long as you live and do not perform more than ordered; do not lessen the time following desire, for the wasting of time is an abomination to the spirit.

You will find rest from vain fancies if you perform every act in life as though it were your last.

The season of failure is the best time for sowing the seeds of success.

Nothing is more precious than being in the present moment. Fully alive, fully aware.

Time is a sort of river of passing events, and strong is its current; no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away.

If people tell you that you should live your life preparing for the future, do not believe them. Real Life is found only in the present.

Either you run the day, or the day runs you.

You must live in the present, launch yourself on every wave, find your eternity in each moment.

What you are is what you have been. What you will be is what you do now.
