 explicitly recognizes the importance of reason in making human life better. And once that happens, what do you get at the same time? You get a scientific revolution and you get an industrial revolution. And you get whose reason? Who reasons? Eric said something about digesting. We can't digest collectively. Can we reason collectively? Is there a consciousness up here somewhere that is collecting all our consciousnesses in which we reason? Now, who reasons? Individuals. Each one of us reasons. We each have a mind. We can share ideas. We can feed off of each other. We can trade intellectually. But it's us as individuals who are the only ones who can actually reason. So it's not an accident, too, that the age of reason leads to a political revolution that's about individualism, which is what the founding of this country is about. The right to life, liberty and the pursuit of happiness. You're right. Each one of you as individuals. Not some collective right. You're right to life, liberty and the pursuit of happiness, right? So the age of reason leads to industrialization. It leads to individualism. It leads to that. You don't get that until reason is discovered during the Enlightenment. Before that, if you think of the way... Think of the poorest people in the world today. I don't know Africa, Asia, wherever. Probably Africa. That's how everybody lived 300 years ago, pretty much. I mean, there were some people who lived up here, but they were talking about income inequality. Income inequality was really dramatic back then, right? The kings and then everybody else. But everybody else pretty much lived subsistence farmers like the poorest people in the world today. Just to give you a sense of how, you know, in a sense, not really lucky, but how much we benefited from the fact that this happened. This is all before us and we're benefiting from it. So reason. Reason of what makes everything we have around us, these lights. I mean, Thomas Edison's reason, right? We get electricity. We get the light bulb. I mean, Benjamin Franklin. Without his work, we wouldn't have electricity. We wouldn't have a light bulb. These buildings, architects, somebody had to figure that out. Again, no gene. But everything in your life is about that. Everything in your life needs to be figured out. You don't have an instinct for mating. We don't. It's hard, right? You've got to figure it out. I mean, you've got to talk this morning about some strategies around that and how to think. How to think about relationships. That was the whole point. How to plan. And it's really crucial. This is about thinking. Even when talking about how to think about yourself and how to undo maybe certain psychological issues, it's about thinking about yourself. There's no other way. They have these rooms that all pattern. You go and you yell and you scream and you bang on the walls. It's fun, but it doesn't help you. The only self-help is from figuring out what the problems are and figuring out what the solution should be. Thinking, thinking, thinking. So if you really want to be properly selfish, not the lying, stealing type, but the type who takes care of self, then the number one value, the number one virtue has to be thinking. Has to be taking reason, taking rationality seriously. Taking your own mind seriously. So we're here about cultivating a body and that's great. About how to eat right and how to have a good physique. And you need that, right? Because you need to be healthy in order to do anything in life. But to really achieve something in life, to really be good at what you want to be, you need to use your mind. You need to figure it out. Even when it comes to diet and exercise, right? Who are we bringing? Who is being brought up here? It's people who've studied it, who've done research, who've figured it out, right? They've used their mind. They've used reason in order to figure out diet. And if you spend, you know, a lot of us spend a lot of time reading diet books and reading nutrition books and looking at the labels and figuring out what we can and cannot eat. And we spend a lot of time figuring out what kind of weights to use how many times a day to exercise, or how many times a day, how many times a year to exercise, I guess it's going to be, right? Because the whole idea is you shouldn't exercise too much. But you know, what kind of weights and all this stuff, right? We spend a huge amount of time on that. Well, what I'm saying is that's the kind of time and thought and effort and energy that needs to be spent on every aspect of your life. Every aspect of your life. What kind of career do you want? What am I really good at? And it can't just be about the money. I mean, money can be important, but it can't just be about the money because believe me, if you set the career goal, if you set your goal as I want to make a million bucks, but the only way to do that and get a million bucks is to do something that I hate doing, getting the million bucks is not going to be satisfying. It's not going to be fun. You're not going to enjoy yourself. Rather be poorer and do something that you love doing than be rich and hate what you're doing. It's about the process. It's about what you love and understanding what you love. Take Eric. He could have gone and invented a light bulb or something, right? But he loves teaching. And you know how much they pay teachers? Nothing. I mean, it's like one of the poorest professions out there. True or not, right? Yeah, absolutely. But he loves it, right? So, I mean, I can guarantee you he's happier standing in front of a classroom teaching on a regular basis and making less money than going out and working, I don't know, on... What would you... I don't know Eric well enough to know what he would have done otherwise. You know, I would have done. I've got a PhD in finance. I could have gone to Wall Street. I could have gone to Wall Street. But I would have been bored in Wall Street. This is much more fun than making millions of dollars in Wall Street for me, not necessarily for you, but for me. I wouldn't exchange my life for life on Wall Street any day. Yeah, I'd have a fancier car. You know, I don't think I could have a hotter wife than I already have. It's true. I'd be married in February. I'll be married 30 years, 3-0 or so. I can't talk about dating because I don't remember dating. So for Ayn Rand, for the idea of truly being self-interested, the key is to think, but to think about everything in life, including, as I said, career. What do I love doing? Why do I love it? Do I love it for the right reasons? Somebody talked about parents giving advice, right? A parent cannot choose a career for you. Cannot choose a career for you have to choose it. And you know, I used to ask, you know, because there's this idea that you should choose a career based on what will do the most good for humanity, right? It's this, again, this 19th century notion. I used to ask my students, how many of you made a list of all the professions in the world and then ranked them based on the social utility where you could do the best for humankind and chose that? And usually there's one poor soul who raises their hand. And then it's to tell the class you selfish bastards, right? Because you chose based on what you wanted to do. But that's a good thing. That's what it's about. Being selfish is not a bad thing. It's done right. It's done properly. It's done fully in what means it means to take care of self. So be rational in everything. Now, what does that mean? Does that mean no emotions? Robots. Like me, right? Emotionalists. No passion. No. Emotions is what you live for, right? It's the emotion. It's the good feeling. It's the happiness. It's the fun. It's the satisfaction. Those are all emotions. Those are all of feelings. That's what you live for. But they're not mechanisms. Your emotions don't tell you what's good for you.
