I can, therefore I am.
If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
Leap, and the net will appear.
The wise does at once what the fool does at last.
To know oneself, one should assert oneself.
The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
Things do not happen. Things are made to happen.
To be a good loser is to learn how to win.
But I don't think we'll go there until we go back to the moon and develop a technology base for living and working and transporting ourselves through space.
