I have been decluttering for about a year now (maybe longer). It is a very slow process with 4 kids. Two weeks ago we signed for a storage unit. We had one a few years ago but cancelled it. The garage is a constant battle and we can't use the weight bench because of it. Our closest storage unit stays full so finally snagged one and will start using it this weekend. We only plan to keep it six months amd will only put things in it we know we want to keep. We live in a cookie cutter house in Florida so no basement and not enough home storage. As we put items in storage we will be discarding quite a bit as well. The plan is to empty the garage, redo the floors, paint, etc. Then reorganize and put back what we keep in the storage unit.
I am constantly discarding items in the house either mailing to our neice, donating locally, or just trashing items. We have been putting out about 3 times the amount of garbage as our neighbors. LoL.
I like the KonMari method just can not do it all back-to-back, and with five bedrooms, room to room works great. I have done categories too. This week I pulled out four old cameras, 2 portable DVD players, 4 old hand held gaming systems. I would like to donate or take to pawn shop. But not sure anyone would want them.
From Christmas to now ago I had DH clean his closet and had 66 shirts (polo and button downs) and 7 suits we took to Metropolitan Ministries. I donate 15 of my dresses. This doesn't include all my kids clothes already donated before the holidays.
Over the holidays we also decluttered the kitchenware and holiday decorations.
One motivating factor is I want to redo my entire first floor from laminate, off-white tile, and carpet to the tile that looks like wood, repaint the interior, change out some furnitire. We have been in the home 13 years and it is time for some upgrades. I plan to declutter and have just the minimum in the house before I reward myself with the upgrades.
