don't pursue endo just because the money.
it is a very stressful career. patients don't want to see you, they're only there because they have pain or problem. Half of endo's schedule is headache. What do GPs refer? pain in the ass patients, difficult to treat canals, GP's ledged canals, broken files, perforations, etc etc.
do ortho if you want good money and happy patients who WANT to come to see you. Most of the ortho I know are happy people.
