The premise of Kondo’s book is that one’s environment should spark joy and that you should feel happy when surrounded by your material possessions. She encourages you to do this not only by getting rid of objects in the tidying push but rather by focusing on the objects that give you pleasure.

Since reading Atomic Habits by James Clear I’ve been obsessed with creating positive systems of habit in my life. He says “You do not rise to the level of your goals, but fall to the level of your systems.” So, while my goal might be to have a successful and satisfying life, that’s just too vague. It wouldn’t be acheivable on its own without an implementation plan.
