To know oneself, one should assert oneself.

To be a good loser is to learn how to win.

You never know what motivates you.

Leap, and the net will appear.

The dog that trots about finds a bone.

The wise does at once what the fool does at last.

Without hard work, nothing grows but weeds.

Quality is not an act, it is a habit.

It's always too early to quit.
