There was a scene in a Jeff Goldblum movie, where his new girlfriend asked why he never changed his clothes. He answered that he did change his clothes, and she should look in his closet. She found that he had 7 identical sets of clothing and shoes. He explained he got the idea from Einstein. It saved him from having to make decisions about trivial things. Like what he should wear.
I always did that sort of thing with watches and pocket knives etc. Same functional watch. Same knife. I bought, sold, and traded lots and lots of knives, but only carried one. Since I joined this site, I wound up with quite a few more knives that I don't really carry much. Why did I buy anything, since I already had what I was going to carry? I never could turn down a deal. Use them or not. Keep them or swap them off, I don't have much invested. So, I don't fret about it. Best wishes. G
