This is enough. Do not add, And why were such things made in the world?

If someone is able to show me that what I think or do is not right, I will happily change, for I seek the truth, by which no one ever was truly harmed. Harmed is the person who continues in his self-deception and ignorance.

The happiness of your life depends upon the quality of your thoughts.

The lot assigned to every man is suited to him, and suits him to itself.

A lucky chance is constant in nothing but inconstancy.

It is a ridiculous thing for a man not to fly from his own badness, which is indeed possible, but to fly from other men's badness, which is impossible.

Let it judge that nothing is either bad or good which can happen equally to the bad man and the good. For that which happens equally to him who lives contrary to nature and to him who lives according to nature, is neither according to nature nor contrary to nature.
