It's a fine line between fabulous and ridiculous. And that line's just as keen as the line between perfect and excellent.
I nearly had a mini-meltdown last week. Lots of work, including work for a new editor. Now, I always aim to impress but when I'm handing in my first piece, I want that article to shine. The thing is, I'm not expecting it to be perfect, so that's where I have to reign myself in - I just want it to be fabulous.
I still do a lot of talking to myself when it comes to trying to change annoying habits. I have to tell myself, "No, stop, you've researched enough, just start writing" and "no more edits - if you tweak this any more it'll start looking like Joan Rivers' face". Because there's always something else you can do, something to add, something to take away. But you have to know when to stop and think, "yep, this works". You've got to find that line when it's fabulous, before it crosses over into ridiculous.
