Bad habits happen. I still hold my pen weird when I write, despite the efforts by teachers and my parents to set me straight. My hand doesn't like it the "right" way, so now after years of abuse I have a lovely impression on my right ring finger that's even misshapen my nail. And my handwriting is still just as hard to read as when I was in second grade. o_O
There are also bad habits in another form of writing: TYPING. Remember learning to type back in school? Well ... I retained that information incorrectly. I'm fast, but I know I'm not hitting the right keys with the right fingers. And my biggest problem with typing?? CAPS LOCK. For YEARS (and by years I mean from jr. high up until just LAST YEAR, people) I used the caps lock for ALL of my capital letter needs. That's right. Even for just the first letter at the beginning of a sentence or a name, I would hit caps lock, hit the letter, and hit caps lock again. Extremely inefficient and the source of much laughter when I typed in front of anyone. It took me a good six months or so to break the habit, but after much determination, I DID IT. I broke that sucker. Me and the shift key are tight now. We're like THIS *crosses fingers*.
Another habit I had to work really hard to break is the amount of space after a period. I thought two were standard, but not these days it seems. Only one space after the end of a sentence. ONLY ONE! Too bad half my book was written before I knew about THAT rule (and all of my older writings which I discovered recently when I pulled one back out to work on it). What a nightmare getting rid of all those extra spaces was, and training myself to hit space once instead of twice. But I broke that sucka bee too.
These broken habits may not seem like big deals to some of you, but I shall celebrate these victories. They were hard work! Have you broken any writing habits?
