Forgetting the nuance of what I am thinking

I have put in my server setup description how I created this site and my workflow for uploading documents. The shorthand is that I use VSCode as a "FTPSSH" where I can text edit and automatically upload, then run a command to build the website. In order to keep track of what I want to write about, I have a file where I jot my ideas with 1-2 sentences of what I mean. I constantly do this, and I usually come back a couple days or weeks later to finish my thought. The problem with this is that I regularly have an idea about what I want to say and how I want to say it, but when I go to revisit it, it has lost all of the nuance, or even that it has changed significantly because it makes more sense in my head.

I really feel upset about this because in my head I really am the smartest man in the world, but on paper I think I am the dumbest. If only they could see what is inside my head!
