Everybody has a weakness for something expensive. It could be a penchant for branded products, nice cars, expensive meals, quality produce, music, but we do indulge in these luxuries every now and then. It is important, however, to treat these splurges as a personal weakness. Mr. Money Moustache explains how he sees his own luxury items:

Mr. Money Moustache explains how he sees his own luxury items:
If I were to get used to all of this, to feel like it were my inalienable right to have it, and become unhappy if I could not have it, I would be pretty much screwed. Because at that point, I would have designed a lifestyle so narrow and delicate, that it could easily be toppled by something as trivial as an economic collapse.

And yet people do this all the time. Most people, even. When you borrow money to buy a consumable product, you are instantly teetering atop the ultimate house of cards. You are getting yourself used to the rare luxury of your new toy, even while you are speeding up the treadmill you have to run upon even to get close enough to use it. This is why I laugh and cry with frustration at the absolute insanity of borrowing money for a car, and the fact that ninety percent of Americans do it.
The real trick here is to enjoy your luxuries from a point of strength instead of dependence.
