Hi, I'm in a big dilemma and I've got depressed because of it. The situation is that I loved science since the days that I remember and I wasn't the kind of guy which only dreamed about Medicine, I was fascinated in almost every branches of science, like Physics; Chemistry; Biology and Technology. I remember that first I was more into Electronics and crazy sophisticated circuits; but when I got older and studied a couple of Biology books (I have a book fetish!) and other resources on the amazing structures of cells, organs and living creatures like humans; I've got the feeling of "Yeah! I should become a doctor and I'll discover an awesome fact or method that I'll be awarded for it.". I was dreaming all about to become a discoverer and a famous scientist. I'm from Iran and here we should take a very hard and stupid competitive exam (it's called "Concours"in French; because some part of Iranian terminology is based on French ones) once a year to enter into the top universities and top fields like Medicine; Dentistry and Pharmacy, just like the big "Gaokao" exam which held annually in China. I tried this crap 2 times and I failed to enter into a Medical school, like my other friends who buried their dream of becoming a doctor. Now I'm a Software Engineering student and I like it, but sometimes I think about the other side of my interests, I mean all the biological stuff that I used to enjoy learning them. I still find myself watching Ted videos or Khan Academy's health and medicine vids about different fields all about Biology. I don't want to experience another "Concours" and I don't know if I have the mental strength of bearing sad things in medicine even if I got passed in the entrance exam, but on the other hand, I don't want to end having fun in the world of Biology... I'm thinking about blending computer and biology, something like Bioinformatics? Studying Biology in Iran is just a waste of time, and it pays almost nothing! that's the fact that even the native experts of biology told me. So I decided to study computer software engineering, I feel comfortable with computers and I'm versed with them because of my childhood interest. I know for a fact that studying medicine in America is expensive, so I don't think everybody could afford their tuition and probably some people won't be able to study medicine. My question is: Does loving Science and Biology mean that you should become a doctor? Every time I see a living creature, I become curious and amazed that how it works better than any human made machines! Do you think that I can still enjoy my interest in Biology, Physiology, etc. with my tech field? or should I forget about them? Thanks and Please Respond!
