Maartje's Ten Golden Rules 1. Keep a picture in your mind of how you would like your environment to be. 2. Only keep what supports your life now. 3. Remember that most things are replaceable. 4. Give everything a home (and return it to its rightful place after use). 5. Define what you are going to keep (amount of space, number of items). 6. Know what you have. 7. Think twice (and sleep on it) before you buy something new. 8. Be in touch with your environment (look, listen and feel). 9. Have nothing on the floor or the bed that doesn't belong there. 10. Treat everything you own with care and attention.
