The dividing lines are there, between each instantiation of "I", even if I can never quite get a glimpse of them. If I squint just so, fast-forwarding through the events of a past self, I don't quite reach a boundary so much as reach a gap. After which another "I" instantiates itself. The dividing line is there; I'm sure of it. But it only seems blurrily visible when I don't focus on it. As soon as my eye approaches, it disapparates into the ether.

One of the greatest joys I've personally experienced is that feeling you get when you genuinely change your mind. It's especially rewarding when you can feel the dominoes falling as each step in a logical sequence causes you to change your mind on increasingly complex lemmas after a basic premise's truth value switches.

I recently read a four year old article by Eliezer Yudkowsky on why Many Worlds survives Occam's razor. The argument was persuasive enough to cause me to change my mind on a stance I've held for nearly two decades.

I subscribe to a lot of podcasts. I use podcasts to keep up with the news, learn more about the world, and expand my mind generally. As such, I've sampled and stopped listening to more podcasts than most people have even heard of.
