You never know what motivates you.
Be kind whenever possible. It is always possible.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
Who seeks shall find.
Begin to be now what you will be hereafter.
Expect problems and eat them for breakfast.
By failing to prepare, you are preparing to fail.
Either you run the day or the day runs you.
Be thine own palace, or the world's thy jail.
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.
