U.S. News & World Report has published their list of the 13 most promising jobs, and the 13 most overrated careers.
I remember being a young 20-something trying to discover my "purpose" or "calling" and exploring all of the options that would fit my Meyer's-Briggs Personality Profile. I remember how poorly my high school and college career services centers prepared me for the career search, and how even more disappointed I became when I realized that my dream of becoming a Hollywood cinematographer would probably never be achieved (especially in light of my poor scores in the "creative" and "analytical" portions of the MB test).
So, what does every good person without career prosepects do? He/she attends college to discover their purpose.
Well, this US N & R report takes some of the guesswork out of career planning. It seems to me that if your recent high school grad were to outline any of their goals or map some of their personality traits, they could find any number of specialities to become or consult some of these professions. I think with the resources available to any graduate, it's going to be easy to find a niche.
You'll notice too that some of the glamorous jobs (i.e. attorney) aren't so glamorous.
