I do have some keepsakes tucked away somewhere. I have my high school diploma, yearbooks, and newspapers. I don't know where they are though so they're not really meaningful to me. What about pictures? My wife loves pictures and I like taking them too. But important to me? Not really. I just don't care much about a visual representation of a memory. What about art or music? I love both but there's a lot out there and easily replaceable. I don't own anything of real monetary value so that factors in to this too. I think my book collection would hurt me if I were to lose it, but not that much. I used to have an impressive baseball card collection but I sold it in college to pay for tuition. I have 24 notebooks which my students have written in, one book for each year of my career. I like having that.
I think this apathy to "things" comes from when I was 18 and decided that I wanted to live my life with the ability to pack my all of my belongings into my car at any given moment. At 48, that's not realistic but I think I have remnants of that wish in my DNA.
So what do I value? My family. My friends. My freedom. My ability to read, think, and write. My wife will probably think that I'm dead inside because I'm admitting to my ambivalence toward photos and our daughter's artwork. Maybe she's right but I don't feel completely dead inside. Maybe like 45% but not all the way.
