In day-to-day life, you have stimulus to behave unethically, but in the long term, it always pays off to be ethical.

Maybe I was accepted to Harvard only because of my tennis skills, since I definitively had no great academic achievements. I was 17 and only thought about surfing and playing tennis. I had almost never left Rio de Janeiro and had never been to the United States.

The three short years I spent at Harvard, where I lived with excellent people, taught me not only that I must know how to choose my partners but also that choosing excellent partners is a skill you can learn. Obviously, when you spend time with the best, you learn how to choose among them.
