To know oneself, one should assert oneself.
Wherever you are - be all there.
Problems are not stop signs, they are guidelines.
Either you run the day or the day runs you.
Expect problems and eat them for breakfast.
Go for it now. The future is promised to no one.
You never know what motivates you.
Begin to be now what you will be hereafter.
Things do not happen. Things are made to happen.
What you do today can improve all your tomorrows.
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.
