Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
I can, therefore I am.
Without hard work, nothing grows but weeds.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
Leap, and the net will appear.
Courage ought to have eyes as well as arms.
He preacheth patience that never knew pain.
