Be thine own palace, or the world's thy jail.
Never complain and never explain.
Leap, and the net will appear.
Who seeks shall find.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Know or listen to those who know.
Wherever you are - be all there.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
Triumphant science and technology are only at the threshold of man's command over sources of energy so stupendous that, if used for military purposes, they can wipe out our entire civilization.
