Ramit Sethi warns against making multiple large financial changes at once (e.g., buying a house, a car, changing jobs) because this sharply increases expenses and complexity. He contrasts short-term, reactive behavior—focusing only on the month—with the wealthy tendency to plan ahead, and advises caution and planning to avoid financial trouble.
This is a pattern that I frequently hear from people who are not particularly savvy with money. They make a lot of changes all at once. House, car, job, all of these things at once. Sometimes you can't help it if you get laid off. It's not like you could plan for that. But in many cases when I talk to people who are in financial trouble, they do not sit down and make a plan for even one year. They often will simply focus on the month and they will buy whatever is in front of them. One characteristic that distinguishes the very rich from almost everybody else is that they plan ahead before they need to. Again, some things cannot be planned for, but often if you're talking about a house and a car in the same year, that is a massive increase in expenses. It's also a massive increase in complexity. You want to be very careful about doing all of that at once.
