Loving what you do is great, but knowing your career will be there tomorrow is even better. And when it comes to booming fields, the health care industry is one that's primed for growth.
In fact, the U.S. Department of Labor estimates that the health care and social assistance industry should create 28 percent of all new jobs between 2010 and 2020. And when it comes to the industry itself, heath care is expected to increase by 33 percent (that's 5.7 million jobs!) between 2010 and 2020.
