Interestingly, the article also highlights the importance of having a Degree. This is crutial for those who think that the certification alone can do the trick. Sure you maybe able to earn a somewhat comfortable salary, but then you will have to rack up the years of experience in order to be comfortable. Let me take liberty of quoting something from the article (as posted by Chris).
Most respondents have completed at least some college work. About a quarter have completed only a high-school diploma or technical training. Nearly 9 percent have earned an associate’s degree. More than 36 percent have earned a bachelor’s degree, and 22 percent have earned a master’s or doctorate. There’s no arguing that the more education one pursues, the higher his or her salary grows. A doctorate-level degree generates the highest average income among respondents, at $68,160, while those respondents who reported having a high-school diploma only earned $43,150 on average. Those with a four-year bachelor’s degree earned an average $53,320.
Free Thinkers are those who are willing to use their minds without fearing to understand things that clash with their own customs, beliefs for privileges. This state of mind is not common, but it is essential for right thinking; where it is absent, discussion is apt to become worse than useless.
