Why do people fear de-junking their living spaces? Why does it usually take trouble to inspire them to get motivated to clean up? As a professional housecleaner of thousands of homes stuffed with things, I can give you the reason and save you the cost of a therapy session. The answer is- fear of regret.
I see it all the time. They are afraid they might need it someday. If they don't let it go, it's always there (who knows where) to be found and possibly used for something. Trust me- It's a thousand to one chance you will truly need it. On the other hand, I can produce lots of evidence to show how keeping things can destroy your marriage, mental state, and respect. Don't waste valuable time on imagined remorse. The freedom of clutter outweighs the risk many times over, so let it go! Get your life back!
