Expect problems and eat them for breakfast.
Know or listen to those who know.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Only the educated are free.
Wherever you are - be all there.
You never know what motivates you.
Never complain and never explain.
The wise does at once what the fool does at last.
I can, therefore I am.
Before you can win a game, you have to not lose it.
