This is not a thing but a service : house cleaning. An extraordinary investment which relieved me from something I hate to do extensively. I do not like to own things, but if I had to single out something : a simple kitchen robot which slices and chops things for me. Also a good mattress, hard and not that expensive. What I should invest in but somehow never have the time : a finance advisor, I am bad with money and have zero interest in the subject (I sure like to have lots of money, just not to deal with it)
