I think my quirk has something to do with the dominant Left Brain side of me. Yeah, that's the scientific/analytic side, not the artistic/creative side. In that case, maybe it has nothing to do with quirky artists--just my dominant brain coming through in a quirky way. See what you think. My Quirk: I play with letters when I'm revising/highlighting. Words that change before my eyes fascinate me. It's a visual stimulation. For a brief instant, it gets in the way of my Right Brained flow during revisions.
Here's what I mean: I'm changing 'have' to 'leave' and I start highlighting the word to replace it when I notice that several letters are the same. have → leave = __ave
These don't even rhyme but my eye tells me I don't have to replace the whole word, just some of the letters. If the letters to change are within one swipe of my cursor, I'll leave the ones that already exist. Maybe it's a fairness issue. Wouldn't want those letters that can stay on the page to get unnecessarily wiped out when they were there first, now do we?
