To know oneself, one should assert oneself.
Only the educated are free.
Be gentle to all and stern with yourself.
Begin to be now what you will be hereafter.
To be a good loser is to learn how to win.
The secret of getting ahead is getting started.
The dog that trots about finds a bone.
Be thine own palace, or the world's thy jail.
Expect problems and eat them for breakfast.
Know or listen to those who know.
I think one of the downsides of the sort of obsession with romantic love and personal fulfillment is that the plain fact of the matter is that those feelings don't last for ever and so they better be replaced and reinforced by things that do.
