The website JobsRated.com recently released a list of the top jobs in America today.  They evaluated a series of around 200 occupations and scored them on 5 "core criteria" - Environment, Income, Outlook, Stress and Physical Demands.

The top 3 jobs are very closely related - mathematician, actuary, and statistician.  Does this mean that we should all go out and become math majors?  Absolutely not.

The problem with these studies is that they assume that people are all gifted in the same way.  If someone is more artistically gifted than analytical, it is doubtful that becoming a mathematician would work out well for that person.  If you're not blessed with math skills, you would probably end each day very drained and would not make much money over the long run. 

The best job for you is a job consistent with your personality profile and passion.  I happen to have a B.A. in Mathematics, but that still does not imply that these jobs are right for me. 

Yes, the job descriptions are very consistent with my personality traits.  However, I have found that work that is not linked to a personal passion can be very draining as well.

Thus, my recommendation is to take this and other job ranking surveys with a grain of salt.  The best way to find a career that is right for you is to undergo a process of learning how God wired you and matching your gifts and abilities with a career about which you are passionate.
