I have often wondered how it is everyone loves himself more than the rest of men, but yet sets less value on his own opinions of himself than the opinions of others.
~ Marcus Aurelius - [Self-esteem]

Remember how often you have postponed minding your interest, and let slip those opportunities the gods have given you. It is now high time to consider what sort of world you are part of, and from what kind of governor of it you are descended; that you have a set period assigned you to act in, and unless you improve it to brighten and compose your thoughts, it will quickly run off with you, and be lost beyond recovery.
~ Marcus Aurelius - [Self-interest]

To understand the true quality of people, you must look into their minds, and examine their pursuits and aversions.

To live happily is an inward power of the soul.

A man's life is what his thoughts make of it.
~ Marcus Aurelius - [Thoughts and Thinking]

Very little is needed to make a happy life; it is all within yourself, in your way of thinking.
~ Marcus Aurelius - [Thoughts and Thinking]

One universe made up all that is; and one God in it all, and one principle of being, and one law, the reason shared by all thinking creatures, and one truth.
~ Marcus Aurelius - [Truth]

Adapt yourself to the things among which your lot has been cast and love sincerely the fellow creatures with whom destiny has ordained that you shall live.

Remember that what pulls the strings is the force hidden within; there lies the power to persuade, there the life -- there, if one must speak out, the real man.

If you are distressed by anything external, the pain is not due to the thing itself but to your own estimate of it; and this you have the power to revoke at any moment.

A man should be upright, not be kept upright.
~ Marcus Aurelius - [Integrity]

If it is not right do not do it; if it is not true do not say it.
~ Marcus Aurelius - [Integrity]

If you are pained by external things, it is not they that disturb you, but your own judgment of them. And it is in your power to wipe out that judgment now.
~ Marcus Aurelius - [Judgment and Judges]

And thou wilt give thyself relief, if thou doest every act of thy life as if it were the last.
~ Marcus Aurelius - [Life and Living]

Let men see, let them know, a real man, who lives as he was meant to live.
~ Marcus Aurelius - [Life and Living]

The art of living is more like that of wrestling than of dancing; the main thing is to stand firm and be ready for an unseen attack.

Your life is what your thoughts make it.
~ Marcus Aurelius - [Life and Living]

Loss is nothing else but change, and change is Nature's delight.
