Hey, don’t laugh, it’s a key skill. The only creepy thing about it is I can look at someone right in the eye and be muttering to myself at the same time. And even though I have at least another 40 years before I’m at that station in life where muttering is just something you do, I’m getting an early start because I’ve discovered that it has high value. I’m not the first to discover this, as it turns out. Experiments have been done to prove that regularly talking to yourself is a positive thing: http://newsfeed.time.com/2012/04/25/talking-to-yourself-may-actually-be-a-good-idea/.
