For as many jokes as there are about writers not writing, writers work so hard. They put their heart and soul into their work, as well as their time and energy.
I think writers literally just feel bad whenever they aren’t writing. I mean, there are many days where I will work all day and feel like I still didn’t do enough.
So stop feeling bad about what you haven’t done and start realizing what you have. Feeling bad isn’t going to help you. It will just bog you down.
