So I want you to think about this. You make 3 agreements anytime that you start Day One, whether it's conscious or subconscious, you make 3 agreements. And the first agreement that you make is this: you come to agreement with that, with this fact: you don't know everything, and you're willing to invest heavily into knowing the things that you don't know. You're willing to invest in knowledge. So you understand this thing: I don't know everything I need to know, so I'm willing to invest in knowledge. If you get 25 years into one industry, you'll find that a lot of leaders don't have that same mindset. Today, they've got to have that mindset if they're going to be successful.
