People find it hard to let go of stuff. Even if its junk they would prefer to store it somewhere rather than sell it for scrap. Even things they know they will have absolutely no use for during the rest of their lives. So people spend more money in building or extending their garage where they can put their junk in cardboard boxes that later gets infested by insects of all sorts. Well, what I tell people is not to invest money in building anything or extending anything. Just get metal buildings that are easy to assemble and dismantle without much stress. At a later stage when you decide to get rid of stuff and free up some space, you will find that you have all that empty space and the money you spent on extending your garage is wasted. When it is a metal building, you could always sell it and have it transported it to the buyer’s location.
