This. I talk to myself all the damn time, sometimes in my mind, often out loud when I'm alone (it's this sort of mumbling). I've been doing it since I was a kid and it helps me focus on things, but I realise it's kind of weird. I'm always fully aware of the fact that I am talking to myself, but I can't stop. Once I tried to force myself to refrain from mumbling (hence only think to myself), and it worked for a month or two, but I slowly fell back into it. Ah well, I guess it does no harm..
I've been using AoB on my main for over half a year now, have gotten all game avvs and 40+ trophies thanks to it, have had scores reviewed dozens of times and still going strong.
