“Laughter is one of the very privileges of reason, being confined to the human species.”

They only are wise who know that they know nothing.

Tell a person they are brave and you help them become so.

Silence is as deep as eternity, speech a shallow as time.

One life; a little gleam of Time between two Eternities; no second chance to us for evermore!

A man without a goal is like a ship without a rudder.

Show me the man you honor, and I will know what kind of man you are.

Speech is silver, silence is golden.

Not what you possess but what you do with what you have, determines your true worth.

Do the duty which lies nearest to you, the second duty will then become clearer.

Conviction is worthless unless it is converted into conduct.

A person with a clear purpose will make progress, even on the roughest road. A person with no purpose will make no progress, even on the smoothest road.

Make yourself an honest man, and then you may be sure there is one less rascal in the world.

The merit of originality is not novelty; it is sincerity. The believing man is the original man; whatsoever he believes, he believes it for himself, not for another.

Nothing is more terrible than activity without insight.

Egotism is the source and summary of all faults and miseries.

Weak eyes are fondest of glittering objects.

Give yourself a break. Stop beating yourself up! Everyone makes mistakes, has setbacks and failures. You don’t come with a book on how to get it right all the time. You will fail sometimes, not because you planned to, but simply because you’re human.

Nobody is more dangerous than he who imagines himself pure in heart; for his purity, by definition, is unassailable.

I could go days, weeks, without talking to another human being.

Before I speak, I have something important to say.

It’s amazing how much panic one honest man can spread among a multitude of hypocrites.

Experience is merely the name men gave to their mistakes.

The future of humanity is going to bifurcate in two directions: Either it’s going to become multiplanetary, or it’s going to remain confined to one planet and eventually there’s going to be an extinction event.

That wasn’t any act of God. That was an act of pure human fuckery.
