The most effective way to do it, is to do it.
By failing to prepare, you are preparing to fail.
Problems are not stop signs, they are guidelines.
What you do today can improve all your tomorrows.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
Never complain and never explain.
Always desire to learn something useful.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
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.
