According to Obama

"Focusing your life solely on making a buck shows a poverty of ambition. It asks too little of yourself. And it will leave you unfulfilled."

"Faith doesn't mean that you don't have doubts."

"Making your mark on the world is hard. If it were easy, everybody would do it. But it's not. It takes patience, it takes commitment, and it comes with plenty of failure along the way. The real test is not whether you avoid this failure, because you won't. It's whether you let it harden or shame you into inaction, or whether you learn from it; whether you choose to persevere."
