Know or listen to those who know.

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

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

If you think you can do it, you can.

The dog that trots about finds a bone.

To know oneself, one should assert oneself.

If you're going through hell, keep going.

Begin to be now what you will be hereafter.

By failing to prepare, you are preparing to fail.
