If you think you can do it, you can.
Be thine own palace, or the world's thy jail.
Quality is not an act, it is a habit.
Things do not happen. Things are made to happen.
Problems are not stop signs, they are guidelines.
Go for it now. The future is promised to no one.
Only the educated are free.
Wherever you are - be all there.
What you do today can improve all your tomorrows.
Always desire to learn something useful.
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.
