Funny thing about clutter: It will eventually find it's own destiny.
I, too, struggled with clutter. Couldn't seem to throw things away, so I'd "store" things in my garage.
When things started feeling unmanagable, I'd move!! Yes. I would sell my house and move. LOL This would force me to clean that clutter. Now, if that isn't enough, When my clutter couldn't fit into my new home, I'd pay for it to be stored. And as you might figure, time would go by so fast, I wouldn't be missing anything, and before I would know it, I'd lose the whole darn storage for failure to pay on time!!
Yes, I can review my loses (which I painfully do from time to time) OR, I can look at the learning experience behind it: You can't lose a whole lot, if you don't have a whole lot.
Or better yet, my lack of will power to keep things orderly, has been mostly due to the fact that when things start piling up, it's so over-whelming, I can barely make a move.....it so naturally sounds Feng Shui....anyway, I know things have tendancy to replace themselves, but it has become so serene and easy to manage now that my clutter is gone. I really have changed. My need to "keep" things is very managable. I like simple things now, and I feel my life is richer for the experience of my clutter loss!! (and also much tidy-er)

(AND, I'm not spending so much time straightening up anymore!)
