To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
To know oneself, one should assert oneself.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
Know or listen to those who know.
You never know what motivates you.
