I worry, that my post is not good enough or might be boring or that I'm wasting my time and even that my photos will take too long to load and people will be annoyed! (Note, I did have someone tell one time my photos were too large and my post took a long time to load!) Anyway, like you said after I hit post, then everything is fine... Blogging should be about what you want to share and not worry about the rest.
