If I lived without it for however long it was in storage, or in a closet, garage, attic, etc., then I don't need it in my daily life. If it was something that not using all that time was an inconvenience, but I settled for it thinking I could be using it later, say once I had more counter space to keep the blender out instead of in the back of a cupboard where I don't want to hassle getting it out, then I keep it. If it's something that can definitely come in handy and save me money like a ShopVac, then I keep it, even though I don't use it all that often - it still saves me money if I have a mess such as water in the basement and I don't need to call someone.

The best gauge is if you haven't used something in several months (and definitely a year or even two), you don't need it! The other tip is to have an objective person help you! It really helps if they can question you and have you see things in stark reality. If you are having trouble, definitely ask for help, even on here. You can always ask me, if you want, but really, it's better, and more efficient, lol, to have the person there with you. Treat them to a meal or something to show your appreciation because not many people want to spend their day(s) going through others people's stuff.

As for getting overwhelmed, sure I do! I find that what works best for me is to set small interim goals. So, going through an entire closet first and finishing that, or doing the bathroom would be another. It depends on how much stuff you have. You might be able to tackle an entire room, including the closets and furniture, but someone else with lots packed in there, might get overwhelmed without parsing it into smaller tasks which would be the closet, or just one dresser, for example.

I def get overwhelmed ! Still have not found a way to deal with certain items. I have slowly done it though. Usually if I can find it a "New" home it helps. If someone else can benefit from it, it makes me feel better.
