First get to know what are your interests. What are the subjects that inspire you, how you see yourself in future as a professor to spread knowledge, an engineer, a Counselor, or a painter. Join career counseling classes or personality development workshops where the experts gives you ideas and activities which help you think in the direction where you want to or motivate you to take a step towards your goals. Education is not just textual, it is something that you actually learn in the outer world, focus on the practicality part of the the study. What you are good at already, and what you like doing are two different things. So remember that. Do what you like and not get into any field just because you are already good at. Of course you can enhance your skills more wisely in that area but sit back and think if that is what you exactly want to do, if it excites you everyday morning when you wake up.
