The notion that a renaissance man is more important today than ever is presented in recent Research by Burning Glass Technologies. Perhaps the best renaissance man of all time was Leonardo da Vinci, who was highly esteemed for his broad knowledge of many fields. The research concludes that we must all become more da Vinci-like in our careers. Said another way: learning a single skill in isolation has a short shelf life. Learning complementary skills becomes critical in what the research describes as a hybrid job economy.
