Or in my fiction writing, I'll always wonder if I forgot something important. Then I hope beta readers find it. I usually don't forget; I'm pretty good at keeping things straight. Although I was just editing a first draft of a work in progress and a minor character changed names.
This isn't just in my writing. Late in June this year I worried that I forgot to pay my estimated taxes (due June 15th). But I, of course, had.
It's frustrating to always be waiting for the other shoe to drop because I'm not sure I did something right, when I did.
I don't know if I second guess myself more than other people. I have the feeling I do.
Do you second guess yourself a lot? Let me know in the comments below.
