"Luck" is random. For the most part (statistical average) most of us have normal "luck". So in the long run, those who have "good luck" are those who have made intelligent choices. Sometimes "luck" runs against them. But most of the time "luck" obeys statistical norms, and they win more often than those who make unintelligent choices.
