My best bull market advice: don't upgrade your lifestyle too much You might afford the Lambo/Ferrari/Porsche now, but think about insurance, taxes & maintenance costs – don't go for liabilities that provide short-term gratification. A Mazda MX-5 or Toyota Supra is just as fun, at only a fraction of the cost. Want to move into a bigger house? Consider the increased costs too — including heating during winter and property taxes. You wouldn't want to pay your entire bear market wage on something that is unnecessarily big for what you really need. Eating better food and staying healthy are much better investments on the long run. Also, drastic changes in your lifestyle will inevitably change your social life. Some friends will no longer relate to the new you and leave, while others will come along trying to take advantage. Family members will also have greater expectations. Staying humble isn't just a meme, it's wise advice on staying happy. Also, research the stories of people who won the lottery. Very few of them ended up living wholesome and fulfilling lives.
