Everything that I need, I keep them into luggage and cartons. Clothes, books, shoes, old stuff, old letters and music albums. When they are kept in luggage and cartons, I can stack them up in a tiny storeroom or a corner so that I have most of my space open and unoccupied. And when I sweep and clean up my place it could be very easy and quick.
Some minimalists in Japan go to the extent of having only a few shirts and pants. In other words, they need only one tiny carton to live on. But that is unrealistic in Southeast Asia, where climate is hot and humid, sometimes you just need to change your shirts after a lot of sweating walking down the streets in Malaysia or Indonesia. In other words, you always have clothes more than what you need for seven days.
It is never easy to become a minimalist. In 2016, I spent a month or two to clear half of my stuff and kept the other half. What I have now is a roomful of stuff. If being a minimalist is a sort of exam, I think I could only get a C at best. When I find the energy to clear things up again, hopefully this year or next, I can clear half of what I have now and keep the other half. Or at least clear out another 20 per cent.
One big clue is this: novels that are available in library, feel free to give them out to friends and book-exchange clubs.
