I may not be the most fastidious housekeeper, but I could never be accused of being a pack rat. I don’t mind Legos strewn about if the kids are playing and having fun or laundry that needs to be folded and put away, but I am not a fan of closets that throw up upon opening or cabinets chocked full of stuff I don’t use.
Keep a donations box handy. Label a large box “Donations” for depositing items you wish to get rid of. Clip a piece of paper and a pen to the box so that you can itemize the loot you are donating. This makes tax time easier.
Go through one room a day until you have uncluttered your whole home.
If you don’t wear it, get rid of it.
If they don’t play with it, chuck it.
If it is trash, just throw is away. This is a big one. Really, just throw it out.
