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.

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

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

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.

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

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

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

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

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.

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

Real living is living for others.

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

One of the strongest motives that lead men to art and science is escape from everyday life with its painful crudity and hopeless dreariness, from the fetters of one's own ever-shifting desires. A finely tempered nature longs to escape from the personal life into the world of objective perception and thought.

The great moral teachers of humanity were, in a way, artistic geniuses in the art of living.
