It totally depends upon your requirement and age. As we progress in life, our requirement changes, for a fresh college graduate, money is more important than anything else. For him/her, ability to make out money from any source is possible and where they find it more, they pursue the career. Very less often, it happens that teenagers are given a chance to follow their own dreams, as in India, the whole career option thing is very much decided by peer pressure. For example: In case, you wish to become a poet, neither your parents nor your friends will suggest you to pursue a career like that. You will be asked to pursue a degree in Technology and thereafter start a career and flourish and after all this, in case you are still passionate about poetry, then you can do something about it. Here the problem is, after you settle down your career in one stream, it is really difficult to start afresh even part time for something else. It totally depends upon your determination if you can pursue your career, from the day you pass out from school.
After explaining all this, lets come back to your question, one needs to follow their dreams and choose that they love, as after some initial years of struggle money will follow sooner or later. In case, one has enough patience to sustain or go through the struggle phase then follow the dreams else go for the job that fetches more money.
Simple isn't it?????
