I can, therefore I am.

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

Be kind whenever possible. It is always possible.

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

Know or listen to those who know.

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

If you think you can do it, you can.

To know oneself, one should assert oneself.

Begin to be now what you will be hereafter.
