You have to have the kind of personality where you're resilient and you can get up and keep moving and learn what there is. What I tell my employees is, 'I want you to make mistakes. If you're not making mistakes, you're not trying hard enough. But, when we make a mistake, let's all study it. Let's all learn from it. After that, we want to make different mistakes. We don't want to keep making the same mistakes.'
