Never complain and never explain.

To know oneself, one should assert oneself.

Quality is not an act, it is a habit.

Things do not happen. Things are made to happen.

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

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

It's always too early to quit.

Be kind whenever possible. It is always possible.

The dog that trots about finds a bone.
