It depends. My brother in law is a doctor and he loved going to class everyday. He now has to do continuing education and he enjoys those too. My mom wanted to be in the medical field but hated school. She became a lab technician as a result because back then it didn't require more than one year of college. She was paid much less than being a doctor would be but she also didn't have the headache of school.
I think you have to ask yourself what you really love to learn about and find a job that uses that. If you would rather do than learn, find a trade school or certificate program in the medical field. Look at your local big hospital's job listings and see the variety of jobs they have. Find some that look interesting and look at what qualifications they require.
