Our bodies are changing every second, our mind and intellect are constantly evolving, and the world gets reinvented at a never ending pace. But when we try to hang onto the past by hanging onto the tangible things that represent who we used to be, we don't adapt to change and we suffer.
When I was a kid, I used to subscribe to MAD magazine. I don't think I could have gotten through my school years without MAD magazine. When I went off to college, I took the MADS with me. The thing is, the MADS stayed in the box. I never took them out. My mind was gorging itself on the brand new information I was learning in my college classes.
Half way through my first year, I realized the presence of the MAD magazines felt like dead weight. It was hard for me because I had a lot of memories of the laughs and insights I had with the MADs. In some ways, they represented my first steps of intellectual independence. But then I realized that the MAD magazines were essential back when I originally read them, and they had done their job, and now they could go. So I offered the MAD magazines to one of my friends who had been openly envying them. He happily took them off my hands.
