According to me, it depends on the interest of a person. If someone has an interest in Law or English, becoming lawyer, clerk, judge, law or English professor would be a good profession for him or her. If someone has an interest in Science subject, becoming doctor, scientist, chemist or a science professor would be a good profession. So, there are many doors open for each profession, but it depends if you have an interest on that subject.
Like my taste is in Law, so I’ll take Law related subjects in University in order to become a barrister. What I want to articulate is, go wherever your interest takes you. As far as the subject Science is concerned, Science could be a great proffession, but only for those who have immense interest in Science. So, 'interest' is the key to choose a right and a suitable carrer. The path would be clear for you, once you find your interest in the subjects you like the most.
