I think so many people end up with all this stuff in this society because we have no time to enjoy good experiences, so we hold on to stuff that we enjoy at least. We barely have any time to do fun things, or to socialize, and the time we do have and schedule to do these things is so tightly alloted (we have to get right back to work after, know we we have work in the morning, we must catch up on sleep debt) it's so hard for our minds to actually relax even we are trying to do those enjoyable things. So we keep stuff in our homes we enjoy looking at or at least hate where we are less.
