I take deep breaths. I focus on my breathing. I imagine when I breathe in light and goodness are filling my body and traveling and touching my innards and going to every corner of my tall, lanky frame. I exhale and blow out all the darkness and negativity and try not to let it hit anyone near me, except maybe that guy who was acting like a prick when he got onto this subway car and jammed his shoulder against my back for no reason. Hey, buddy, why don't you try this little contemplative breathing exercise so maybe you don't act like such an asshole, how about that?
