Nah... you can't really surmise someone on an initial post, the OP explained his reasoning behind his desire not to spend, and it made sense. Some people just don't need things or want them, or get bored fast.
Not everyone needs trophies. I personally think as long as you're happy, that's all that matters. However, I have some relatives who have a bunch of money who never leave the damn house, and I often tell them they need to get out and take a vacation, travel, see the world. What good is an inflated bank account if you never leave your couch?
We don't need fancy cars or mansions to be happy, but we should treat ourselves to things every now and then as a reminder of the hard work we do.
My personal hobby is pinball machines, I collect them, I refinish them, love the mechanics to them. They're pricey, 4-6K for a modern one... I have a game room with a bunch of them, standup video arcade cabinet with 2000 games, pool table, etc. This as a hobby allows me to unwind and digest the crap that goes down every day with AM.
So do you need to buy things to unwind? No.. but you should have an outside hobby or interest and not be afraid to buy the occasional toy here and there.
