I am amazed when I see what some other people feel are their "treasures:" Little League baseball trophies, childhood games and toys, tools they never use, broken things they'll never fix, a breadbox? Anyone using a breadbox hasn't read my blog about how valuable counter space is!
I helped a friend move recently and he put as much stuff into the garage as he did the house!
I do have a few good ideas why people keep such things. I think they tie them to someone who gave them to them or someone they were with when they bought them somewhere in their past. Of course, many people hoard out of fear they'll have nothing one day, or they might need that useless thing one day. But the truth is: we need to get over this stuff! There's always more stuff in our future - the Good Will is full of other people's stuff they wasted their time, money, and our planet's resources on. You won't be young again, and your kids don't want your old toys. Oh, and your old girlfriend's not coming back, so make some room for a new one!
