^ Exactly.
Why do you want to pursue medicine, yet suddenly you changed your mind to wanting to do law? Is it just for the prestige and reputation, or do you genuinely enjoy the two, because there are many other careers which do not require the amount of hard work as these two but which yield a high income (i.e investment banking, optometry). Do you really enjoy the sciencey aspect of things, given the fact that you have chosen NO SCIENCES? Maybe your subject selection is inclined more towards law/arts, given the ancient history and society and culture.
^don't listen to this noob. Investment banking is verrryyy hard. let me capitalise that for you. VERY HARD career path.
The hours are extremely long, but the money, skill, knowledge you get is very good. To me it is also prestigious because usually the investment banks take only the smartest and dedicated people. These people tend to pull off all or mostly HD's at uni. Remember, they were also selected through a rigorous selection process that revolves around working in pressured environments; mathematical, analytical and financial knowledge; ability to learn fast; etc etc.
Medical interviews tend to be more focused on passion and emotions lol. which is very subjective. views differ amongst interviewers.
Also optometry is not easy as you seem to point it out to be...
Don't worry is you haven't done any sciences in the past. You can always make a change and try a science course and such.
Also don't let others deter what you want to do. If you want to do medicine, then at least try for it. but have back up plans...
