Welcomeifitsnotanarse to The Cult!
I think the the first Kondo thread started in September and some posters, who started then, have more or less, finished kondoing. Woohoo!
It's hard to tell how many have completely lost their mojo, but a few have had a wobble with Christmas, NY, illness, etc, but have climbed back on the wagon successfully. Some managed to get their fixes even during the holiday days! 
The real joy of MK's method is that every category/sub-category kondoed, leaves tidy/empty space and much less STUFF. Because we can see success immediately, whether a small category or large one, the excitement continues... so long as the cleared areas remain uncluttered. These clear areas are a constant visual reminder of what our goal is.
Many people find that it gets easier, as their mindset changes, and discarding decisions seem to become simpler.
Having done your own and DH's clothes you will be reminded, daily, of what you have already achieved, and your goal! 
Once you have made a 'home' for everything, by discarding the crap things your don't want, need or use, and trained the family to tidy things away immediately after use, cleaning will be a breeze and you will never have to do massive blitzes again.
You should aim at only bringing essentials into the home, or replacing things. In both cases, anything coming in should also see things leaving.
The reason we need MK is because we have been acquiring too much stuff and discarding too little.
