If I understand your question correctly, you want organization & order in your life, but when your environment gets too "sterile" it causes you anxiety. The rest of my response is based on this assumption.
I too enjoy going to other people's houses, & seeing how neat & orderly they are. I then come back to my clutter-catastrophe & want to make it the same. There are a few problems with this -
1. If you simply "organize" with the intention of getting things out of sight, they don't necessarily get put in a logical place, making finding/using them more difficult, & more anxiety-inducing.
2. Many people think that to de-clutter, you need to get rid of stuff. Letting go of your belongings can involve very deep, personal, emotional responses, making the process very difficult.
3. While the idea of clean surfaces & everything tucked away & out of sight is very positive and motivating, to actually do that your space may strip it of your personality, making you feel lost in your own environment.
So, don't try to make sweeping changes at one time, and don't think that you need to be like The Joneses to achieve organization. Baby steps.
1. Is some of your clutter due to things that actually HAVE a place to go being left out instead? Or not tossing trash? (my husband is notorious for leaving the wrappings of food packages laying on the counter when he is done cooking) Identify these things, & change the behaviors. Remind yourself to rinse your dishes & put them in the dishwasher when done, instead of stacked in the sink, for example. Take 5 min each evening to go through the main rooms in your home & put away the clutter that has a home (I find this is a good baby step leading to eventually putting it back when you are done with it. It's hard to jump right to that 2nd step initially tho, so doing it once a day gets you to the same place in the end, & your brain will start to register those items that are always pulled out & need to be returned - you'll end up putting those away as you go naturally after a while)
2. Do you have actual junk that needs to be gotten rid of? Go ahead & toss it - you've already identified it & let go emotionally. Do you have some "big ticket items" that you don't just want to toss, but no longer need/want? Put an ad on Craigslist, or one of the "for sale" groups on Facebook. (holding a rummage sounds like a great idea, but there is a LOT of work that goes into those, storage of items until the big event, & then you are letting go of so many items at one time, it might be more anxiety producing than helpful at this point)
3. Once you have gotten #1 & 2 underway, pick 1 or 2 surfaces that it is important for you to have clean & clear so you can use it - maybe one of the counters in the kitchen for prepping food, or a sofa table in the living room so you can set your purse & keys down when you get home w/o losing them. Pick an item or two to keep there that is a part of your personality in some way (your coffee maker or a set of unique canisters in the kitchen, a pretty dish for keys & spare change on the sofa table). That way, even when the surface is clean & clutter free, it is still reflective of YOU, and encourages you to keep the rest of the area clear to show it off.
Finally, if you are anything like me, you have enough clutter to keep you occupied for a while, to the point that you don't know where to begin. The thought of tackling this can be overwhelming to the point of causing us to NOT address it. Write down an area you want to work on - either space or behavior. And then break that down further. Use that as a starting point.
For example, organizing your entire kitchen might give you a nervous breakdown. But wiping down the stove every night after cooking is doable. In order to do that, you need to remove pots/pans/dishes from the stove. So now maybe your sink & counters are cluttered with dishes. So moving on, loading the dishwasher with dirty dishes every night is doable (once you take care of the 1-time backlog) And so on - each new step you add to the process is doable, because it builds on something you've already taken care of & have under control.
