Be kind whenever possible. It is always possible.

I can, therefore I am.

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.

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

The dog that trots about finds a bone.

By failing to prepare, you are preparing to fail.

Know or listen to those who know.
