try a new challenge: how little can you spend? (money....) try not buying stuff for a while, or buy just the most basic... you'll see how good it feels after a while....
Yep it's surprisingly easy to get along with what you already have, make do / repair / alter old things, do a little preparation before you go anywhere so you won't have to buy anything... it's fun and guess what - it saves you money too http://en.wikipedia.org/wiki/Buy_Nothing_Day
people buy too many things... the government loves it... keeps the economy going and the people broke
