This is the best organizing/de-cluttering book that I've read in a long time, perhaps ever. I don't have ADHD and it was still super-helpful. This will be the book I recommend to others if they're asking about this topic. Here are my take away principles (because, yes, it was so good, I took notes):
1. storage solutions should be easy, obvious, and in the place where the stuff will be used.
2. use open shelving, clear bins, labeled (but not fancy), as little stacking as possible
3. You must use employ the "brutal purge" - reduce, reduce, reduce in order to make de-cluttering last. You should have empty space (i.e. purge until you have excess storage space); cutting back on inventory is far better than having good storage solutions.
4. Store everything as close to the place of use as possible - my action step for this? Get a bin for dishcloths and another for dish towels to put under the kitchen sink, then I'll have no need to fold them ever again. Just throw them in!)
5. everything should be efficient, simple and easy to maintain
6. Use non-lidded bins on shelves (easy to access/put away); eliminate stacking. Clear is the best (then no need for labels) or open front bins with solid bottoms are even better.

Steps to organizing any room/area/space: PREPARE/SET-UP (bags for donation and trash, find space for piles like "other parts of house" and sort out the stuff that does belong in the room), PURGE, CLEAN, NAME (name the space and designate areas "plate shelf" Mug shelf", REDUCE (as necessary to have a small enough keep pile to fit in the space), PROCURE (necessary storage tools ie. shelves, bins, hangers, etc, they don't need to be fancy, just functional), RETURN (appropriate items to the space), PUT AWAY/CLEAR AWAY (all other piles to elsewhere in the house, trash, etc.) BASK (in my hard work and lovely space!)
