Luck is just one of many terms used to describe someone accomplishing something that is statically unlikely. Saying someone was lucky does diminish the task if it is a mischaracterization of an event. I think there is a both a place for luck and hard work. If I role dice six times and get snake eyes all six times is that skill or luck? Luck. Is Jeff Gordon winning lots of Nascar races luck? Nope. The are many events that happen that are unplanned, like meeting your significant other. Is that luck or fate or skill?
