How strangely easy difficult things are!

Silence is the severest criticism.

To make pleasures pleasant, shorten them.

Experience shows that success is due less to ability than to zeal.

Concentration alone conquers.

Success soon palls. The joyous time is, when the breeze first strikes your sails, and the waters rustle under your bows.

The first duty towards children is to make them happy. If you have not made them so, you have wronged them. No other good they may get can make up for that.
