(Except the part about how debt is "how you get rich")
And yet, I'd wager than 90% of people who attempt to replicate your success story would wind up worse off for having tried it.
The problem is that it comes with a huge risk of screwing with your head. And it's very difficult to detect and correct when this is happening.
I've had my success stories playing games with debt too. Gaming low rates, churning credit cards, and so on. I see people around me do the same things all the time.
The only trouble is, the next day these same people are:
* Allowing debt to influence their purchasing decisions (e.g. buying a larger car, a larger house, and so on)
* Trying more sophisticated "experiments", only to get burned
In other words, they scored a minor victory in an inconsequential battle only to lose big later on.
