And about good food/travel, what makes that different from buying expensive shit? Is it not the momentary happiness of buying the item that is similar to that of eating a good meal or traveling to a new place? Fond memories are nice, but they are just that, memories.
Well, food is a continual experience. It's everyday, food is very important to me. I wasn't saying you should prioritize the same things I do, I was using my own interests as an example. Clothes, cars, plasma tvs can be fulfilling if they hold significance to you.
Traveling again, is an experience and continual for me. I don't just go, and sate myself on those memories, I just like to go around.
In the end, experiences enrich you, the individual, while stuff doesn't necessarily stick with you. There's always exceptions where you have a few favourite things and will never part with them. You can't adopt someone else's lifestyle choice and think you'll be happy, just find what works for you.
