To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
I can, therefore I am.
Things do not happen. Things are made to happen.
To be a good loser is to learn how to win.
Who seeks shall find.
Problems are not stop signs, they are guidelines.
If you can dream it, you can do it.
Do not weep do not wax indignant. Understand.
I think that somebody with the resources and innovation and the idea is going to come out of nowhere and come up with a successful space travel program.
