I'm a walking OCD xD
Learning to live with my obsessiveness/compulsiveness helped me control most of those aspects, and I do enjoy the occasional quirk (such as the π above!) xD

Oh dear, you're not alone! There's lots of us out there and you know it. Καθένας μας με τις παραξενιές τους, τις μεγάλες και μικρές του! :)
