Be gentle to all and stern with yourself.
Leap, and the net will appear.
It's always too early to quit.
I can, therefore I am.
Be thine own palace, or the world's thy jail.
Know or listen to those who know.
The dog that trots about finds a bone.
Wherever you are - be all there.
The secret of getting ahead is getting started.
Do not weep do not wax indignant. Understand.
Science is a differential equation. Religion is a boundary condition.
