Dear Self: Nobody Is Going to Read Your Notebooks.
This is definitely a reminder I need from time to time. My pocket notebooks are never going to be part of the public record. I will never have to defend the half-thought things I dumped in a pocket notebook. Nobody will ever be impressed by what I wrote unless I work it into something bigger, and even then, it's unlikely anyone will ever much care.
So I can just write. I can just catch little things, regardless of state of finish or polish. The inner editor isn't allowed in my pocket notebooks.
