“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.”

“You can’t let your failures define you. You have to let your failures teach you.”

It's about the friendships you make, the bonds of trust you establish and the image of America that you project to the rest of the world.”
