Some days you're the bug, some days you're the windshield.

We must be willing to fail and to appreciate the truth that often 'Life is not a problem to be solved, but a mystery to be lived.'

The knowledge of oneself will preserve that person from vanity.

Never throughout history has a man who lived a life of ease left a name worth remembering.

The natural world is the greatest source of excitement. The greatest source of visual beauty. It is the greatest source of so much in life that makes life worth living.

Live as if you were living a second time, and as though you had acted wrongly the first time.

How people treat you is their karma; how you react is yours.

Those who want to live, let them fight, and those who do not want to fight in this world of eternal struggle do not deserve to live.

Don't go around saying the world owes you a living. The world owes you nothing. It was here first.

No one has ever become poor by giving.

I restore myself when I'm alone.

Each life makes its own immitation of immortality.

Life is not a problem to be solved, but a reality to be experienced.

Three things have been difficult to tame: the oceans, fools, and women. We may soon be able to tame the oceans; fools and women will take a little longer.

All of us are products of our childhood.

Life swings like a pendulum backward and forward between pain and boredom.

What goes up must come down.

It is not the length of life, but the depth.

Life would be tragic if it weren't funny.

I have always regarded myself as the pillar of my life.
