From book, 'Out of the Crayon Box' (living vibrant, organized lives). They have a website. Their philosophy is "Do more living, not more work!". They simplify everything into 6 steps (Declutter first; then Organize, Maintain, Observe, Refrain and Enjoy!). Biggest steps Declutter & Organize, are easy the way they do it. Then it's putting things back where they go, with a simple (not complex or tedious) system which they teach. 'Observe' teaches to evaluate what works for you personally.
They encourage you to become generous...making a habit to donate (if an item still in good condition) or to toss it away whenever you bring an item into your home...so it never becomes cluttered again. Cleaning is so easy now and my family & I love the space we regained!
