excuse the tangent, but if you want to think about what luck is or isn't, i highly recommend spending forty intense/breezy minutes on netlflix watching this documentary -- long shot:

^ luck -- its kind of like a glass half full, glass half empty debate. maybe how you think about it is who you are. was the long shot guy lucky because somebody he knew found a great advocate for him? or that what happened at the ballpark that day was all just luck? or was it because he's a baseball fan and goes to the games? etc., etc. ---
it really makes you think about the topic -- is luck one thing? or a combination of things??? if the latter, when does it not become luck?
just don't think too much, because you can drive yourself crazy! personally, i think the advocate sums it up perfectly well at the very end of the documentary.
so anyway -- long shot, check it out, its well worth your time!
