You become what you give your attention to...If you yourself don't choose what thoughts and images you expose yourself to, someone else will, and their motives may not be the highest.

It is the nature of the wise to resist pleasures, but the foolish to be a slave to them.

What is the first business of one who practices philosophy? To get rid of self-conceit. For it is impossible for anyone to begin to learn that which he thinks he already knows.

If you want to improve, be content to be thought foolish and stupid with regard to external things. Don't wish to be thought to know anything; and even if you appear to be somebody important to others, distrust yourself. For, it is difficult to both keep your faculty of choice in a state conformable to nature, and at the same time acquire external things. But while you are careful about the one, you must of necessity neglect the other

Concerning the Gods, there are those who deny the very existence of the Godhead; others say that it exists, but neither bestirs nor concerns itself not has forethought far anything. A third party attribute to it existence and forethought, but only for great and heavenly matters, not for anything that is on earth. A fourth party admit things on earth as well as in heaven, but only in general, and not with respect to each individual. A fifth, of whom were Ulysses and Socrates, are those that cry: -- I move not without Thy knowledge!

No man is disturbed by things, but by his opinion about things.

Do not laugh much or often or unrestrainedly.
