It's always too early to quit.
Wherever you are - be all there.
The secret of getting ahead is getting started.
Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
Begin to be now what you will be hereafter.
Without hard work, nothing grows but weeds.
Be kind whenever possible. It is always possible.
I can, therefore I am.
The most effective way to do it, is to do it.
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.
