If you think you can do it, you can.

To know oneself, one should assert oneself.

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

Know or listen to those who know.

The dog that trots about finds a bone.

Leap, and the net will appear.

Without hard work, nothing grows but weeds.

Never complain and never explain.

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