I've recently taken a lot more responsibilities at work and one of my duties is to email people for paperwork, or documents that we need from them. I'm not very good at emailing so I tend to spend about 5 minutes brainstorming, writing, and editing before I send it off. I probably read it about six or seven times. I don't think I have OCD, it's just that I want my message to be clear and concise. btw I do the same thing with poasting and text messaging but, because it's totally casual I tend to not be so anal about wording and grammar.
