I highly recommend Katherine Gibson's book "Unclutter Your Life: Transforming your physical, mental and emotional space" as a gentle way to ease into the organizing realm.
Ms. Gibson writes about clutter not only affecting our homes, but also our emotional well-being. At the end of each chapter, she presents strategies to tackle the clutter surrounding one's life.
The book offers a holistic approach to life organization and transformation in small, easily digestible bites. Beautiful food for thought!
