How do you know what you want?
ajju: I think you have already honed in on the basics: "You have to actually do it". If it seems like there are too many things to try and they all look appealing, you just need to understand yourself better and self observation will help you there.You are wrong to suggest that we grow to like anything life forces us to do. If you have an analytical mind, a job flipping burgers or pressing buttons as a tester is never going to satisfy you. You might be able to change the job to something you like more (e.g. write test scripts) but that's a whole other topic.Some additional things I have learnt that may be useful for you are: (1) There is no one thing predestined to be your calling in life, there are several things you may like. (2) If you really want something, you'll usually get it eventually or find something that you like better.It is useful to set a long term goal based on what you know you like so far and at least initially, while you are still in college, it is useful to state it broadly but don't tie yourself to a specific way of getting to that goal.For example, I know I enjoy coding, technology, business and teaching. There are several combinations of these that could end up being my calling. The specific image I may have in mind is to work as an engineer / technical entrepreneur now and become a teacher later in life, but I am sure there are other configurations where I would be able to satisfy all of my urges (e.g. a venture capitalist who focuses on technology and guides entrepreneurs and writes code for fun a.k.a pg).Your short term or "localized in time" options are always going to be restricted by your circumstances. You pick the best out of those options based partly on your understanding of yourself which will evolve with time (use pg's suggestions above/below) and (rarely) on your current needs. (e.g. You may have to choose a higher paying job to repay some loans even though you like the other one) but if you keep your long term goal in sight and don't lose hope on that, you'll be able to steer your way to it even if you get diverted temporarily by short term needs.
