Be gentle to all and stern with yourself.
The dog that trots about finds a bone.
Know or listen to those who know.
Begin to be now what you will be hereafter.
Be thine own palace, or the world's thy jail.
If you think you can do it, you can.
If you're going through hell, keep going.
It's always too early to quit.
What you do today can improve all your tomorrows.
You never know what motivates you.
