- If you talk to an artist and say, Why do you paint? Why do you dance? they don't understand the question. The answer they give is, I can't not, right? There's compulsion. And not all ideas have compulsion. They don't feed our souls. And I think for-- and probably shared by a lot of people in this room. The question is, what ideas should we be stubborn with, and what ideas should we know when to quit? And I think it's often a debate. You have to know when to quit, and you should never quit. And I think the answer is, if you can't stop thinking about it-- if the idea has so much soul that it just compels you, those are the ones that we never quit, where the other ones-- sure, you can sort of figure out a time to walk away. And that is what this became for me. It was something I couldn't not do. And when you have that kind of belief in something, desperate belief-- and people have it in their families. They have it in their faith. They have desperate belief in something. The criticism becomes part of the fun, frankly. I mean, the story you're talking about is true. It happened in the early days when I was talking about Start With Why. I was on a stage talking to a fairly large group of entrepreneurs and business owners, and the very first-- it wasn't a question. The very first statement made when we went to Q&A-- a guy just-- with the microphone said, I think you're naive. I don't think you're-- you've never run a multi-billion dollar company. I think your ideas are useless in the real world, and I don't think it'll ever work. And my answer was, so don't do it. - [LAUGHS] - Next question. And it's not because I'm-- was being difficult. It's because I never saw my job to convince people because I don't think I'm right, and I don't think that I have answers. I think I have a point of view. That's all. And so I'm simply sharing my point of view. And if you don't share my point of view, I'm totally fine with that, you know? If you want to run your business your way, you run it your way. I just think business could run this way. And so I never took it personally, quite frankly, when I got comments like that or when they questioned my credentials or anything like that.
