How do they do it?

So I'm watching "Bourne Identity," and Jason Bourne has just gone to his apartment. He is an extreme minimalist, to be sure. His kitchen is complete with all the NEEDS of a chef, but no frills. No art, plants, or anything else that might not be considered a "need." It got me thinking. I know he's a book/movie character, and his character, by nature, would only keep what was absolutely needed, but this minimalism thing really resonated with me. I have a really strong desire to be that way, a total minimalist, keeping nothing but the bare essentials. I envy those who can lead that lifestyle. Sadly, my heart wouldn't allow it. I am far too emotionally connected to things, especially the things belonging to those loved ones who are no longer with me in life. From pictures of my family from way before I was born, to my grandpa's brown, felted cowboy hat, I just cannot let certain things go.

I also have this completion complex. Poor Jason. I have difficulty purchasing a piece of a set and not buying the entire set of things. The quickest example of this I can come up with is in scrapbooking. When I joined Stampin' Up (years ago), I had to buy every color of paper and ink they had, along with the matching markers. Even though I still, to this day, haven't used a few of the colors, I knew I would have to have them, just in case. Or it would bother me -- REALLY bother me. It honestly stresses me out if I do not have a complete collection of something I know I will use. In fact, just on Thursday, I was using a navy blue marking pen and my teammate asked where I had gotten it. I told her I had purchased a 24-count multi-color pack of these pens. She said she really liked the navy pen. Later that day, I went back to my classroom and dug in my desk, knowing I had a second navy pen to give her. Why? Because I lost one of the pens from the first set and it drove me crazy, so I went and bought a second set so that I could replace the color.

So I have 3 questions:

A) Does this make me crazy?
and
2) Does anyone else have this issue?
and
D) How does one become a minimalist? Is it genetic? Is it regional? Does my mid-western upbringing mean I will never be able to not have "stuff" everywhere?

Luckily, I am not in danger of being on any of those hoarding shows.
