“I was once a fortunate man but at some point fortune abandoned me.”

Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.

Dwell on the beauty of life. Watch the stars, and see yourself running with them.

A person’s worth is measured by the worth of what he values.

If any man despises me, that is his problem. My only concern is not doing or saying anything deserving of contempt.

Everything that exists is in a manner the seed of that which will be.

Whatever anyone does or says, I must be emerald and keep my colour.

Very little is needed to make a happy life; it is all within yourself in your way of thinking.

The memory of everything is very soon overwhelmed in time.

The impediment to action advances action. What stands in the way becomes the way.

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

The best revenge is to be unlike him who performed the injury.

You always own the option of having no opinion.

Look well into thyself; there is a source of strength which will always spring up if thou wilt always look.

Do not act as if you were going to live ten thousand years. Death hangs over you. While you live, while it is in your power, be good.

A man must stand erect, not be kept erect by others.

It never ceases to amaze me: we all love ourselves more than other people, but care more about their opinion than our own.
