I hear and I forget. I see and I remember. I do and I understand.

So many people have this idea: I want to achieve something great or be somebody great. And they neglect the step that leads to greatness. They don't honor this step at this moment because they have this idea of some future moment where they are going to be great.

Everything we hear is an opinion, not a fact. Everything we see is a perspective, not the truth.

Never ruin an apology with an excuse.

Don't take tomorrow to bed with you.

Everything excellent is as difficult as it is rare.

Each day is a little life; every waking and rising a little birth; every fresh morning a little youth; every going to rest and sleep a little death.

All great achievements require time.

Promises are like crying babies in a theater, they should be carried out at once.

Beer: The cause of, and solution to, all of life's problems.

What a man does for others, not what they do for him, gives him immortality.

Science is organized knowledge. Wisdom is organized life.

When you judge another, you do not define them, you define yourself.

No act of kindness, no matter how small, is ever wasted.

I don't like definitions, but if there is a definition of freedom, it would be when you have control over your reality to transform it, to change it, rather than having it imposed upon you. You can't really ask for more than that.

The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?

Why fit in when you were born to stand out?

A house is not a home unless it contains food and fire for the mind as well as the body.

To me, being an intellectual doesn't mean knowing about intellectual issues; it means taking pleasure in them.

Don't criticize what you don't understand, son. You never walked in that man's shoes.

The only real mistake is the one from which we learn nothing.
