Hi, all through high school, I was going to pursue Medicine for the job security and other perks etc. that it offers. (Note that I'm from India and out here Medicine is not a PG degree unlike in the US) I do not have any love for the field so to speak. I do find it interesting (I find all of science interesting but in the decreasing order of Physics, Chem and Bio.) but there isn't some kind of inner fire that burns within me that urges me to become a doc. Now all through this, I was constantly reminding myself of the fact that I wouldn't become a physicist as I had originally planned. Now after a great deal of heartburn, I have decided that I won't do Medicine and will pursue a career in physics. Namely BSc, MSc and then a PhD. But now I'm feeling that I'm making a huge mistake by leaving Medicine which is pretty much like a pot of gold. A job is ensured and there won't be any financial struggle either. (Again in my country we have govt. run medical colleges which can provide you a medical education for as little as 1000-2000$ a year. Of course, the entrance exams are competitive but I know I can get through.) I'm reading up a lot on the net and people are saying that most Physics PhDs are unemployed, and all this is very discouraging. Am I making a huuuge mistake?? Also can I branch out after a Phd in physics and do anything else? eg Media, Finance or Computers. Is a Phd in CS more advisable??
