By failing to prepare, you are preparing to fail.
Who seeks shall find.
Leap, and the net will appear.
Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
Know or listen to those who know.
If you can dream it, you can do it.
Never complain and never explain.
Problems are not stop signs, they are guidelines.
To be a good loser is to learn how to win.
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.
