But, as this article points out, it's easy to trap yourself with the things you like. Like fishing? You buy a huge boat. Like flying? You spend millions on a cool plane. Like scenery? You buy several houses.
Pretty soon, all your time and energy goes into the things you own. Or, as people say, the things own you instead of you owning the things. John puts it very well: you can only live in one place at a time.
Once my startups begin to mature, I plan on renting just about everything. That way I can try many different things without the pain of ownership. If I find myself doing something over and over again -- and it would have to be dozens of times -- I might consider buying something permanently. Maybe.
Concentrate on experiences, not possessions (or money)
EDIT: I heard somebody refer to what happened as a "luxury consumption trap." Just wanted to add that nothing about this has anything to do with the amount of money involved. This is more about your relationship to the things you own, however much they might cost. You can tie yourself up with five dollar items as easily as you can five million-dollar items. (It's true, however, that people seem especially blind about this when this happens with larger-ticket items.)
