It kind of depends on your mortgage rate. If your rate is low it technically makes more sense to invest your money, as that'll have a great return. If your mortgage rate is high, you might be better off paying extra each month against the principle as it'll drastically reduce how much you pay in interest over the course of the loan.

You could do half that, make minimum payments if you want, and invest the rest. But either way, you find yourself in such immense control. You could lose half your income and not change your lifestyle. Or retire early. Or take bigger risks.

I’ve always been fascinated how people decide what kind of home and car and such they go for. It usually seems to be: as big as I can go. And then you’re not really that more secure. I guess you can sell your home and find something smaller, but that’s hard to do at any time with kids in school, let alone during bad times.

That doesn't necessarily mean lever up. But it does mean take that extra X% you'd put into your mortgage and place it in some CDs/Bonds/whatever. Or even better, if inflation is still higher than the current rate you could even use it to buy an investment property and then pay that off as slow as possible as well. Let the banks hang themselves being long the dollar!

Debt is only bad when you're losing. The problem is it takes a level of sophistication to understand when you're winning. Hence, the need for Ramsey-type all-or-nothing solutions.

What’s interesting is the idea that some people take on a lifestyle based on their income and they leave themselves no flexibility.

This is often the case, but not always. It also doesn't account for the much better sleep I get at night, or the unshackled feeling I experience knowing I am debt free. There's an enormous psychological benefit that is not easily quantified.
