Know or listen to those who know.
You never know what motivates you.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
Never complain and never explain.
Expect problems and eat them for breakfast.
It's always too early to quit.
Quality is not an act, it is a habit.
Every educated person is a future enemy.
