Things do not happen. Things are made to happen.
If you've got a talent, protect it.
By failing to prepare, you are preparing to fail.
The wise does at once what the fool does at last.
Begin to be now what you will be hereafter.
The secret of getting ahead is getting started.
To be a good loser is to learn how to win.
Expect problems and eat them for breakfast.
Be kind whenever possible. It is always possible.
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.
