When you meet someone better than yourself, turn your thoughts to becoming his equal. When you meet someone not as good as you are, look within and examine your own self.
ConfuciusStudy the past if you would define the future. I am not one who was born in the possession of knowledge; I am one who is fond of antiquity, and earnest in seeking it there. Learning without thought is labor lost; thought without learning is perilous.
Confucius
