Live as if you were to die tomorrow. Learn as if you were to live forever.

You should be the change that you want to see in the world.

We are what we repeatedly do. Excellence, then, is a habit.

The key to immortality is first living a life worth remembering.

To believe in something, and not live it, is dishonest.

If A is a success in life, then A equals x plus y plus z. Work is x; y is play; and z is keeping your mouth shut.

If you love life, don't waste time, for time is what life is made up of.

It does not matter how slowly you go so long as you do not stop.

If you always put limit on everything you do, physical or anything else, it will spread into your work and into your life. There are no limits. There are only plateaus, and you must not stay there, you must go beyond them.

If you make an ass out of yourself, there will always be someone to ride you.

Beware the barrenness of a busy life.

Bad men live that they may eat and drink, whereas good men eat and drink that they may live.

Do not do to others what angers you if done to you by others.

Whatever you do will be insignificant, but it is very important that you do it.

The greatest way to live with honor in this world is to be what we pretend to be; and if we observe, we shall find, that all human virtues increase and strengthen themselves by the practice of them.

Success is a lousy teacher. It seduces smart people into thinking they can't lose.

I really like my life. I've arranged my life so that I can do what I want.

Life well spent is long.

Do not go where the path may lead; go instead where there is no path and leave a trail.

If we listened to our intellect we'd never have a love affair. We'd never have a friendship. We'd never go in business because we'd be cynical: "It's gonna go wrong." Or "She's going to hurt me." Or,"I've had a couple of bad love affairs, so therefore . . ." Well, that's nonsense. You're going to miss life. You've got to jump off the cliff all the time and build your wings on the way down.

As a well-spent day brings happy sleep, so life well used brings happy death.

He who is not courageous enough to take risks will accomplish nothing in life.

Ever since I was a child I have had this instinctive urge for expansion and growth. To me, the function and duty of a quality human being is the sincere and honest development of one's potential.

At fifteen my heart was set on learning;
At thirty I stood firm;
At forty I had no more doubts;
At fifty I knew the mandate of heaven;
At sixty my ear was obedient;
At seventy I could follow my heart's desire without transgressing the norm.

Life is hard. After all, it kills you.
