To be a good loser is to learn how to win.
Leap, and the net will appear.
Only the educated are free.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Who seeks shall find.
The most effective way to do it, is to do it.
Always desire to learn something useful.
Be kind whenever possible. It is always possible.
You never know what motivates you.
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.
