Only by joy and sorrow does a person know anything about themselves and their destiny. They learn what to do and what to avoid.

I do not know myself, and God forbid that I should.

A state of affairs which leads to daily vexation is not the right state.

All things are only transitory.

The misfortune in the state is, that nobody can enjoy life in peace, but that everybody must govern; and in art, that nobody will enjoy what has been produced, but that every one wants to reproduce on his own account.

We accept every person in the world as that for which he gives himself out, only he must give himself out for something. We can put up with the unpleasant more easily than we can endure the insignificant.

Limitation of aims is the mother of wisdom and the secret of achievement.
