live a rich fulfilling life well so jonathan really explored that research into hedonic psychology, particularly the implications of does money buy happiness? How can you use money to achieve happiness? And there's an enormous voluminous amount of research on this in very, very obscure academic journals. And when Jonathan started working on this, very few who non-academics were even aware that this research existed. But I would say there's a handful of takeaways from that work, that research. One is that possessions don't generally make people happy. Now, there's exceptions to that. But as a general rule, the bigger house, the fancier car, the painting on the wall, the bigger couch generally don't move people's happiness as much as they expect. And that's really the key is the gap between what you spend and the happiness you expect to get from the spending that causes the disappointment that people feel. And, you know, I think everyone listening has had a similar experience. You know, you've been in a starter house, you see a new house you love, you talk about it with your significant other, you agree, we're going to take the plunge, you buy the house, and you move in and you're just thrilled. And then, you know, a year later you look around and the paint is chipping and, you know, there's like rats in the attic and it's mo' money, mo' problems, right? And the next level beyond that observation that possessions are not the key is that you want to use your money to create experiences with people you love, shared experiences. experiences. You want to use money to create memories. And so you spend your money on things you can do with friends and family, joint vacations, commemorative events, family reunions, things like that. And then it's the final level that Jonathan explored more and more in the later years of his life.
