Excellent post over on Simon Says about how he had pitched an idea to an editor, the editor asked him to revise it, which Simon did and he got the commission! There's dedication for you. The thing is, though, earlier that day, before I read his post, I had a similar situation with an editor and I revised my pitch and got the commission too! There's spooky!
It also taught me a valuable lesson. The editor said that my pitch was too vague and the article would have had too much breadth with not enough depth. The editor was quite right. So what am I going to do about that in future? I'm going to sharpen my pitches and be more specific and clear in them. One article = one topic/theme.
