Sometimes mistakes can be a massive WAKE UP CALL. We writers suffer from them all the time. It could be as simple as having a train of thought be lost because we have no pen, batteries for our keyboards, cell phones away from us or what not. Sure, it sounds like an impossibility due to technology being so accessible - but the reality is IT'S NOT.
Ever make a mistake that just continuously eats away at you? Part of it is because of the backlash you rightfully deserve, but also you let others down. It's really a difficult thing to process, let alone accept. I compare the situation to one of my diving lessons.

What's in a word? A hell of a lot if you follow the Websters-Dictionary Twitter feed. Those people have words, for words divided by words. The rest of us look at words as an involuntary action.

Language, in general, is a difficult thing for many people to master, especially when in a larger country like the USA.
