Learning to live with less (a goal!) UPDATE

Well, I talked to the hubs and he agreed (reluctantly) that we have too much stuff (still).  This has actually been an ongoing process since we moved into the house just over a year ago.  We bought a 1700sq. ft. + size home and it took 2 of those 26' U-Haul trucks to move us out of his parents house and into our own.  Plus a few small truck loads and multiple loads in our sport wagon.  What the heck did we have???  Oh and that didn't include a full size pool table which came separately or about 15 boxes of Star Wars and other 'collectibles' that came out of his old closet which we brought over by car.  I say "collectibles" because a lot of the items are just items, they aren't all vintage or rare, they are just items (figures, vehicles) that exist to be made and purchased.  I'm not bitter at all... (right).
My husband thought about what we moved.  There was a sofa and loveseat, extra refrigerator,  large glass patio table, full size mattress/frame set, entertainment center, 2 shallow but tall DVD shelves from #IKEA, dining table and 4 chairs, and 4 large utility cabinets.  Through craigslist and garage sales, the sofa, patio table, full size bed and dining set are all gone.  So a lot of it was big items that probably took up half or most of one of the truck loads.  However, a 26' truck is supposed to be able to move a 4 bedroom house.  Um, how come I never have anything to wear if I have so much STUFF?
So the last couple nights we went through each DVD in our collection and asked 'Is this our favorite?' (of course White Chicks made the cut!) and we went through our books, clothes, shoes, coats, blankets, linens, extra kitchen items, bathroom things and we still have more to do.  We aren't even hoarders or pack rats, we just amassed a lot of stuff.  We still have the garage to go through again, and the side yard.  I gave us a deadline of two weeks because I plan to have a garage sale and donate what doesn't sell.  We tend to save up for large items we need, right now we desperately need a new love seat.
Having too much makes me cranky, doesn't find in with a #Minimalist mindset and definitely doesn't cater to the 'Modern' look (clean, crisp, fresh, etc.).  Plus I really want to downsize our house already.
Have you gone through this process yet?  Are you willing to?  Thoughts?
