I think the difference between who I am now and who I was when I was a young adult is in the amount of things I’ve noticed. It’s just a sheer quantity. And like Stalin or Lenin or a famous Russian general or Tom Clancy (inside hoops) was fond of saying, quantity has a quality all its own.
As I’ve grown older, my methods of doing anything have gotten more streamlined. For instance, I take the cheese and the turkey out of the refrigerator at the same time now, to avoid having to backtrack, in the assembly of a sandwich.
I’ve noticed the seasons, I’ve noticed the stars, I’ve noticed the cyclical nature of the economy. I’ve noticed that longjohns are good to wear when it’s very cold. I’ve noticed there’s a sucker born every minute.
I’ve noticed things that I couldn’t possibly have noticed when I was twenty. Because some things cycle so slowly that twenty years isn’t enough to see their range of behavior or activity. Just can’t have been done. I might have grasped things in an intellectual way, but there’s just no substitute for experience.
Which is something else I’ve noticed.
