“In recent years, a number of studies and books--including those by risk analyst Nassim Taleb, investment strategist Michael Mauboussin, and economist Robert Frank-- have suggested that luck and opportunity may play a far greater role than we ever realized, across a number of fields, including financial trading, business, sports, art, music, literature, and science. Their argument is not that luck is everything; of course talent matters. Instead, the data suggests that we miss out on a really importance piece of the success picture if we only focus on personal characteristics in attempting to understand the determinants of success.”

My point is that articles such as yours feel more like blaming people for not achieving success as if all things being equal, attaining goals is simply a matter of the right attitude. More importantly, it feels like you are saying a smart, educated and hardworking individual who is unsuccessful is doing something wrong.
Maybe they are just unlucky.
