The secret of getting ahead is getting started.
Quality is not an act, it is a habit.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
Always desire to learn something useful.
Wherever you are - be all there.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
You never know what motivates you.
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.
