Some of the most demonstrable moments of people Killin’ It are simple physical moments.  Take for example this amazing clip of a Phillies fan, on his way back from the concession stand, catching a foul ball with one hand and never breaking stride.  I had to watch this several times in order take in the clean and effortless poetry of this killin’ it moment.  It’s the rare kind of thing that makes me think of stars colliding all at the right place and at the right time.  It also serves as a valuable reminder of how even in the most banal situations (walking back from the concession stand at a ball game, for instance) you may find yourself suddenly massively killin’ it for all the world to see!
