Ahhh, when I use to write fanfic I thought the same way but came to the opposite conclusion.
I am writing for me, I want to write it and read it, and I’ll throw this into the ocean of other fanfics and no longer care if anyone else wants to read it. If they do, it’s there for them.
It’s a good way to look at it, but I find it most difficult to do anything just for me. If I’m not doing something for someone else I don’t care to be doing it at all. That is more than likely just due to my depression though.
