Hello Kekes, every profession is a good profession if you like to do it! My dad is a doctor in medicine (while I'm a doctor in algae). For sure he has a better salary than mine even if he doesn't work at the hospital, in fact he is a general practitioner, a 'family doctor', not a professional man.
Anyway it seems to me that saying 'I want to be a doctor because I want to become rich' is a very sad thing; in fact my father wanted to become a doc because he wanted to save lives, to treat the ill people and comfort them and also because his father was a doctor too and he wanted to follow his steps..he has never cared about money!
Besides I see that his job is very hard and he suffers a lot when someone of his patients dies because of a heavy disease. So since you say 'I don't like medicine', in my opinion you had better find another thing to study, because you must love medicine as my dad loves it and do not think of money!
