The goal is to go through your whole house, in very specific steps (KonMari), and only keep the things that "spark joy" for you. Which essentially means that you will be discarding a lot, but only so your house can end up sparking joy for you.
Spark Joy shows what the first book spelled out, but in much more detail and with illustrations. So while the second book is not a must have if you have read the first it does go to the next step and helpful for those who are not quite clear what Kondo was explaining in words when pictures are more helpful.
The book itself is a bit humorous, though not intended to be that way. I laughed several times when Kondo explained how socks don't like to be balled up and prefer to rest. Or how we need to welcome our house each day when we arrive home. How about wishing each of our items goodbye as we throw them away. I have to remind myself that she is from a different culture which does things differently. Otherwise it just seemed way too "new age" for me.
Starting with clothes you go through each and every piece you own (she recommends you only doing your own items - and letting others do theirs). If you decide you love that piece and it sparks joy, keep it. If not, get rid of it. Once you decide what to keep you fold it up in a certain way which really does save a whole lot of space in your drawers and looks more organized as well.
Then you move on to books, misc., and lastly memorabilia and photos.
It seriously works. After one week of off and on work my bedroom is finally finished! This was my view this afternoon as I took a 5 second break towards the end of the task:
Now it's time for me to weed through my books. This will be a hard challenge!
