To be a good loser is to learn how to win.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
Leap, and the net will appear.
If you're going through hell, keep going.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Who seeks shall find.
I have taught history on the high school and college levels, and am or have been a lecturer at the Smithsonian, The National Institutes of Health, and numerous colleges and universities, mostly on science fiction and technology subjects.
