I use timers constantly. I call my personal rule "There is no later". If I have a thought like "When X i will do Y" or "In ten minutes I will X", I just treat it as near impossible feat like juggling balls on a tightrope unicycle. I've seen people do it, but I don't have any idea how, and I'm certainly not going to make plans as if I knew how to do it.

I pretend that information cannot be transmitted across time except by machines, living things are mind-reset by Cthulhu at random intervals in a manner only studied at Miskatonic University.
