Never complain and never explain.

Go for it now. The future is promised to no one.

Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.

If you think you can do it, you can.

By failing to prepare, you are preparing to fail.

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

Know or listen to those who know.
