Epicurus

Of all the means which wisdom acquires to ensure happiness throughout the whole of life, by far the most important is friendship.

He who is not satisfied with a little, is satisfied with nothing.

Self-sufficiency is the greatest of all wealth.

The wealth required by nature is limited and is easy to procure; but the wealth required by vain ideals extends to infinity. (15)

There are two kinds of pleasure: one consisting in a state of rest, in which both body and mind are undisturbed by any kind of pain; the other arising from an agreeable agitation of the senses, producing a correspondent emotion in the soul. It is upon the former of these that the enjoyment of life chiefly depends. Happiness may therefore be said to consist in bodily ease, and mental tranquility.

The wealth required by nature is limited and is easy to procure; but the wealth required by vain ideals extends to infinity.

If you wish to make Pythocles wealthy, don't give him more money; rather, reduce his desires.

Self-sufficiency is the greatest of all wealth.

He who is not satisfied with a little is satisfied with nothing.

Nothing is sufficient for the person who finds sufficiency too little.
