I had rather never receive a kindness than never bestow one.

He who has great power should use it lightly.

I know that nothing comes to pass but what God appoints; our fate is decreed, and things do not happen by chance, but every man's portion of joy and sorrow is predetermined.

The many speak highly of you, but have you really any grounds for satisfaction with yourself if you are the kind of person the many understand?

Be harsh with yourself at times.

A great fortune is a great slavery.

Let the man, who would be grateful, think of repaying a kindness, even while receiving it.
