Know or listen to those who know.
You never know what motivates you.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
The most effective way to do it, is to do it.

Only the educated are free.
Who seeks shall find.
What you do today can improve all your tomorrows.
Never complain and never explain.
