Never complain and never explain.
Know or listen to those who know.
After a storm comes a calm.
Be kind whenever possible. It is always possible.
Begin to be now what you will be hereafter.
It's always too early to quit.
Without hard work, nothing grows but weeds.
Who seeks shall find.
To be a good loser is to learn how to win.
To know oneself, one should assert oneself.
The whole business of marshaling one's energies becomes more and more important as one grows older.
