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

Begin to be now what you will be hereafter.

To know oneself, one should assert oneself.

Be thine own palace, or the world's thy jail.

Never complain and never explain.

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

If you're going through hell, keep going.

Know or listen to those who know.

By failing to prepare, you are preparing to fail.
