One doesn't recognize the really important moments in one's life until it's too late.

Eventually all things fall into place. Until then, laugh at the confusion, live for the moments, and know everything happens for a reason.

Love is like an hourglass, with the heart filling up as the brain empties

We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.

Life is made up of marble and mud.

A man who dares to waste one hour of life has not discovered the value of life

Without a measureless and perpetual uncertainty, the drama of human life would be destroyed.

Every morning we are born again. What we do today is what matters most.

Don't be too timid and squeamish about your actions. All life is an experiment. The more experiments you make the better.

Life is not an exact science, it is an art.

The privilege of a lifetime is to become who you truly are.

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

The historian looks backward. In the end he also believes backward.

When I let go of what I am, I become what I might be.

A man who dares to waste one hour of time has not discovered the value of life.

Nothing exists except atoms and empty space; everything else is opinion.

I always like to look on the optimistic side of life, but I am realistic enough to know that life is a complex matter.

Your pain is the breaking of the shell that encloses your understanding... And could you keep your heart in wonder at the daily miracles of your life, your pain would not seem less wondrous than your joy

Old minds are like old horses; you must exercise them if you wish to keep them in working order.

We cannot live better than in seeking to become better.

When life hands you a lemon, say, 'Oh yeah, I like lemons! What else ya got?
