The Life-Changing Magic of Tidying Up is a book by Marie Kondo which teaches you the KonMari method of tidying your home. She travels the world as a consultant in tidying and so through her book she speaks to you as a teacher, explaining her methods, her research, and her experiences with tidying. What really caught me was that she claims her method will change your life AND that after doing so you will always live in a tidy home. You will never have to declutter again.
How? Because living in a tidy home will result in also having a tidy mind. These things will go hand in hand with the rest of your life and once you realize your new life, you will never go back.
One thing Marie has you do is state why you want to tidy up. And then to keep analyzing why, delving into each statement until you come to the final conculsion. That you are doing it to be happy. For me, I want to be able to have a room where I can wake up and feel open and comfortable. I want to be organized such that I don’t feel the need to declutter once a year. I want to feel inspired by my space to do the things I love like reading, yoga, drawing, cooking and listening to music. I want to wake up happy to be here. I want to gain more focus in my mind for what career I want to move into and where I want to take my life. Because I want to wake up every day and think today will be a good day.
