What you do today can improve all your tomorrows.
The most effective way to do it, is to do it.
Without hard work, nothing grows but weeds.
Quality is not an act, it is a habit.
Well done is better than well said.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
By failing to prepare, you are preparing to fail.
Leap, and the net will appear.
Go for it now. The future is promised to no one.
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.
