It's silly to try to escape other people's faults. They are inescapable. Just try to escape your own.

The happiness of your life depends upon the quality of your thoughts: therefore, guard accordingly, and take care that you entertain no notions unsuitable to virtue and reasonable nature.

Nothing is worth doing pointlessly.

Men exist for each other. Then either improve them, or put up with them.

The happiness of those who want to be popular depends on others; the happiness of those who seek pleasure fluctuates with moods outside their control; but the happiness of the wise grows out of their own free acts.

Because a thing seems difficult for you, do not think it impossible for anyone to accomplish.

Everything that happens either happens in such a way as you are formed by nature to bear it, or as you are not formed by nature to bear it.
