Onion thing: if it works, it's most likely because the stuff in onions that makes your eyes sting is bad for viruses. The onion-stuff reacts with water (hence stinging eyes) and the viruses will be attached to water from your breath/snot/whatever.
Hmm.
Anyway, hi. I'm not a hoarder (fairly emphatically not, it makes me sick and stressed) but I do have a list of Things That Need Doing Round The House, including a bit of decluttering, and you are providing me with motivation. And inspiration. You're awesome, all of you.
In return for this free motivation, I will attempt to provide some in return. Somebody asked 'what's it like when you get there? When it's done?' Well, I'm not done, but regardless, it's kind of like this.
Imagine coming into your house. Keys in the lock, opening the door, hanging up your coat and scarf and whatnot. Now imagine immediately feeling better, much better, because now you're At Home, and home is a lovely, relaxing place to be.
So you think: hmm, best tidy up. Imagine whizzing around and chucking the odd thing back where it goes in less than 10 minutes, and then sitting down to drink steaming hot tea from your favourite mug in your living room, which contains only those things that pertain to living rooms.
And after this lovely cup of tea? Ah! Doorbell. And someone you know and love was just going past and thought they'd say hi. And you can let them in, make them a cup of tea (with your ample supply of clean mugs) and not be in the least bit embarrassed about anything in your house. Not even if you have bras on the radiator, because...well, everyone has laundry.
Imagine no more clutter, and your house being...lovely. Not perfect, because perfection is static and unchanging. But lovely.
...
One bite at a time, and it will get done. And maintenance? SO MUCH EASIER than getting it there. Honest.
And 
for all. :)
