I had this experience enough times to realize that I was simply terrible at judging whether my work was good or not. And guess what? So are you. You’re just too close to it.
Fortunately, it doesn’t have to matter, as your job now officially has nothing to do with deciding if the work is good. Your job is to do the work, put it out there and let the world decide.
Now, I know that sounds scary. But let’s be dead clear about something: You’re not John Steinbeck (and neither was he, at the start). You have to get there first. And the only way to do that is through practice and criticism. But the only way to get practice and criticism is to make and share your work.
