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

Life is like riding a bicycle. To keep your balance you must keep moving.

Remembering that I'll be dead soon is the most important tool I've ever encountered to help me make the big choices in life. Because almost everything — all external expectations, all pride, all fear of embarrassment or failure - these things just fall away in the face of death, leaving only what is truly important. Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.

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

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

You have enemies? Good. That means you've stood up for something, sometime in your life.

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

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.

There are only two ways to live your life. One is as though nothing is a miracle. The other is as though everything is a miracle.

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.

Not everything that counts can be counted, and not everything that can be counted counts. This was on a sign hanging in Einstein's office at Princeton, which is often quoted as a statement by him; research should be able to reveal whether or not it originated with Einstein.

Only a life lived for others is a life worthwhile.

Nothing will benefit human health and increase chances for survival of life on Earth as much as the evolution to a vegetarian diet.

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

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

Beware the barrenness of a busy life.

A person starts to live when he can live outside himself.

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

A purpose of human life, no matter who is controlling it, is to love whoever is around to be loved.

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

If you live each day as if it was your last, someday you'll most certainly be right. From his speech at Stanford University during graduation in the spring of 2005.

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

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

Why change the world when we can change ourselves?
