Order a 10"X20" or larger shed and move it into your backyard.
Go to your local Goodwill and Flea Markets and start accumulating empty suitcases.
Put your keepable stuff in the suitcases and label each case with what is in it on a piece of blue masking tape and magic marker from Walmart and store the suitcases in the shed.Suitcase label examples are:Knives/Books/Ammo/Misc stuff/Fishing gear/Camping gear/
Kitchen stuff/etc.
Keep several empty suitcases marked "Flea Market" in the shed. From time to time rummage thru the Keepable stuff and move some of it into the "Flea Market" suitcases.Have a flea market sale once or twice a year and what is left over can be dropped off at your local goodwill or salvation army store. You will also benefit by ebaying in addition to fleamarketing.
I found that reducing my possessions became a living cyclic adventure that continues over and over with the passage of time.
I believe that a man who has a strong "collector" mentality, a euphemism for someone who really experiences pain when extracting himself from his things,could probably get along with a shed and 25
suitcases. I am down to a shed and 10 suitcases.

"Actually this is just a place for my stuff, ya know? That's all, a little place for my stuff. That's all I want, that's all you need in life, is a little place for your stuff, ya know? I can see it on your table, everybody's got a little place for their stuff. This is my stuff, that's your stuff, that'll be his stuff over there. That's all you need in life, a little place for your stuff. That's all your house is: a place to keep your stuff. If you didn't have so much stuff, you wouldn't need a house. You could just walk around all the time."
