In my opinion, you have to look for more than one factor. In almost all of the above posts, money is taken as the only factor. Some people have brought prestige into it. Here are things that I take into account: money, prestige, ability to serve/satisfy your close relatives or background. The last one influences me a lot than the first one. You have to evaluate yourself. Would you prefer money or something else in life. Considering other factors is very important because in either of the professions, u will make what you need to survive. A question to you, as I ask myself at times: What will you do in the year to come if GOD comes to you and says that you have as much money as you want in your bank account ? For sure, first few months, you will spend in luxury, and other few months in charity. But after a year? At that time, you need other category that would wake u up every morning. So in my opinion, you have to list all the things that drive you to hard work everyday. Give percentage weight to them. compare the two fields. Choose the better one. You will have some down feelings about the other one, but just remind yourself that the one u chose was the BETTER one.
