If you struggle with keeping your space tidy or if you're trying to declutter, I highly recommend Marie Kondo's book
The Life-Changing Magic of Tidying Up. It's not just about tidying, it gets to the root of the problem and teaches you how to address it and eradicate it forever from your life. It basically explains why we're holding on to superfluous things and how to shift our mindset, and it actually goes beyond the issue of clutter and organization. I'm a big skeptic and when I see the word "life-changing" I'm the first to go "Yeah, right!" but I'm so glad I gave this book a shot. I hope this suggestion will be useful to someone
