ChaNaWiT/ShutterstockTo become a master of something, at least in the academic world, you have to earn your master's degree, which usually requires an additional year or two of schooling after acquiring your bachelor's degree.
Few master's degrees come cheaply, as Business Insider previously reported. According to 2014 study from college planning site EAdvisors, more than half of master's degree holders have student loans averaging $56,661.
