I believe you should study what you love, because you should be looking for a job that you would enjoy doing. If work is what you’ll be doing for the majority of your life, you better be enjoying it or you’ll be wasting your life. Alan Watts has an outstanding lecture that covers the question, what would you do if money were no object? This is such an important question to ask yourself, it forces you to look at what you enjoy solely as enjoyment rather than some materialistic benefit.
