For the past few months, my wife - somewhat reluctantly - and I have been purging a lot of our belongings. I have found that we, people, hang on to the most worthless junk. Now, we never really had a lot of things to begin with, but definitely more than necessary.
So I adopted a new-to-me way of thinking and feeling: If I don't love something, it's history. I don't need it. I don't want it.
We have not owned a television since we sold ours back in 2011. But other things - nick nacks, sentimentald, clothing, etc. - we had. So, recently, we have purged almost the entirety of our wardrobes, and replaced them with more neutral items. I now wear my entire wardrobe in a month (pretty good considering they're only worn on weekends). I have reduced to three t-shirts, two button-ups, two pants, two pairs of shoes, two outer layers. This is great, too, because after having lost 37 pounds in the last year, it is nice to have clothing that fits.
We have gone through the kitchen and our daughter's things, and have gotten rid of quite a bit, and with no remorse. We still have a few things to dump... Such as our printer. It is bulky and takes up valuable space in the closet when not in use. There is a print:copy/scan machine at work that I have access to 24/7. However, it does not print in high enough quality for, say, business cards or photo paper. So we would still need a high quality printer. I think stand-alone photo printers can be had for about $50 brand new, however.
When I describe this to people, they ask: So, you don have any decorations or anything? Wrong. But I do all of the decorations we do have.
We also got rid of our king size bed. We still have the mattress, as we haven't found a buyer for it yet. So the mattress sits directly on the floor. Best night of sleep I have had in about a month (my sleep quality app confirms this).
In the way of small kitchen appliances, we have a KitchenAid blender and a KitchenAid stand mixer. The blender was found at wok an repaired with an $8 part. The mixer was given to us used. That is all for appliances. We don't need anything else. We do, however, have three different coffee makers. All manual. An AeroPress, a Chemex, and a French Press. Each one makes a different type of coffee. And, being coffee geeks, we truly enjoy and love them on a daily basis. Plus, neither cost over $40, and we got them within at least six months of each other.
Those are but a few examples. Basically, we keep nothing that we don't use regularly, and don't love. It helps to keep free of distractions, and keeps upkeep to a minimum.
Edit: Here are a couple of resources by a man who has served as great inspiration for this:
