Know or listen to those who know.
Always desire to learn something useful.
Well done is better than well said.
Never complain and never explain.
The wise does at once what the fool does at last.
You never know what motivates you.
Only the educated are free.
Expect problems and eat them for breakfast.
Go for it now. The future is promised to no one.
Be gentle to all and stern with yourself.
He who rides the sea of the Nile must have sails woven of patience.
