My family deals in cars for a living and enjoys them as a hobby, too. I taught my son early on that there are 2 kinds of cars; commodities and possessions and to not get them mixed up.

We often spend money and time on the possessions that don't necessarily make financial sense. But as long as it's reasonable and enjoyable, and that's how you want to enjoy the fruits of your labor then go ahead. Just don't make that mistake on the commodities.

The difficulties come in when we confuse the 2 at some point or another.
