This might seem obvious to some people, and not everyone will experience this problem. In fact most of my friends have no problems at all 'letting go' of things they don't use. Some of us, though (myself included) find it difficult. For example: until a couple of years ago I had two jewelry boxes, which might be fine, if I owned more than four pieces of jewelry, but I don't. They both sat, empty, through ten years and five moves before I figured out a way to let go.
My jewelry box saga in a nutshell is this: I didn't love the jewelry boxes, I loved what the jewelry boxes represented. My desire to hang on to them had nothing whatsoever to do with pretty accessory storage. It was just one example of my emotional investment in my things. I cried when I took my car to the wreckers. I can't throw out anything with a face, I have to 're-house' it in the garden. I have keep-sake boxes and use words like 'let go of', 'un-own' or 're-house' instead of 'get rid of.' If you can relate, this process might help you attack the 'storage' cupboard.
What You Need
Tools
A camera
A journal or paper
A pen
Instructions
1. Take a photo. It doesn't have to win any awards, it just has to remind you of what the object represents.2. Write down your memories/feelings. Writing down your memories about an item, like when and why you bought it, who gave it to you and why you feel like you want to hold on to it can help you understand and process your feelings.
3. Store the photo and journals until you are ready to get rid of them. Store the journals and pictures so you can look at them again if and when you want to. At some point you might feel like you don't need to keep them any more, then you can un-own them as well. If you do want to hang on to them they will take up a much smaller physical and emotional space.

Good ideas and, after having to sort through multiple households worth of inherited belongings and feeling really stuck, I'll offer this one... I send as much as possible to a thrift store that benefits my local pet welfare group. I keep asking myself 'Would my (insert mother, father, grandmother, friend) be happier that I held onto this item, even though it went unused here, or be happier that it went to help an animal find a new home?' That seems to help me tremendously with letting go of items.
a swap party or regifting with friends is a great way to get rid of things you have a hard time parting with. often someone will adopt your item and love, use and keep it for years to come. their joy in owning your former possession is usually enough to let go.
a dear friend of mine just graduated with her masters. i gave her one of my father's fountain pens. he collected them. i never use them. she loves it and appreciates it all the more having known my dad.
i am totally like this. i have letters written to me in FIRST GRADE.
however, when i moved from east coast to west, i could only take what i could fit into my toyota corolla. i'd spent the last eight years building a beautiful home full of things BELOVED to me, full of memories, so what i ended up doing was having a going away party to which i invited only people i truly, truly love and i asked them to take EVERYTHING. nobody was allowed to leave my bash with empty hands. now, it is intensely comforting to me to know that those objects, so full of memories for me, are now memories OF me for my faraway friends who are treasuring them as much as i ever did. i get little texts now like "used your vintage kitchen scale today and thought of you!" etc. a nice way to extend the emotional life of cherished objects in a new way.
I wish I had read this a month ago. I have just had to downsize as I moved to a smaller house... I was good but I could have been better... I still kept the nest I found when I was 11!!! (let's just say that it has been a very long time since I was 11!)
