To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Things do not happen. Things are made to happen.

Know or listen to those who know.

The secret of getting ahead is getting started.

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

By failing to prepare, you are preparing to fail.

Begin to be now what you will be hereafter.

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