When I work with clients, I often find myself saying, "There's good news and bad news. The good news: getting organized isn't about the bins. The bad news: getting organized isn't about the bins."
In other words, it's great: you can save lots of money not buying bins, boxes, and organizing "systems." And it's also kind of a bummer: you can't just buy bins, boxes, and organizing systems and become magically organized forever.
Getting organized, in my view, isn't really about where you put your stuff. It's about your relationship with your stuff.
It's a process of becoming mindful of what you have, and why you have it, and how it's contributing to your life. Because if it's not contributing - and especially if it's dragging you down somehow - why is it in your life at all?
I was talking to someone just yesterday about her closet, and her clothes collection. She has lots of clothes from her old corporate job, clothes from a more hipster job, and clothes from when she used to play tennis. None of these clothes are relevant to her life now. So why should she have to wade through them every day to get to the stuff that works for her now? In case she returns to that former life?
How often has that ever happened to you - that you saved something for a different "you," and then you returned to being that you? For me: zero times. Most of us are moving forward through life: learning, growing, and evolving. Don't let your stuff keep you back in the past.
