Q: My parents wants me to study science because I am a good student. But I don’t like science actually, though I can probably do well in it. Should I study science?

​There is no easy answer to your situation.  You sound like you are capable of studying science.  But you are not interested in it.  Did you used to be interested and you lost your interest?  Or, you are someone who is not really interested in any subject, but can study well anyway.  I would say it is not possible to guide what is a good solution until we have more information on what you ARE interested in, not only that you are NOT INTERESTED in science.  If you don’t study science, what will you study?
I might be giving you the oldest philosophical advice when I say “Know yourself.”  If you do not know your interests and skills, you cannot give a good direction to your life.  And if you cannot give that direction, someone else will!    So, you can to give attention to the process of learning about yourself, not just about subject they teach in school.
At Insight, we advise students a simple model of self-discovery: reflect >engage >repeat. Reflect on your interests, what makes you happy, when have you been touched by an intense emotion?  You can , ask your parents, your friends, your siblings about their thoughts.  But reflection is not enough, you must get out of your head and enter the world.  Engage in some activity that you are interested in.  Really take part and to discover how you feel.  Did your interest increase or wane?  Now, you are reflecting.   This back and forth between action and reflection will help you better understand yourself.
Then, you would know what to do.  It is said, "Not having a plan, puts you at the mercy of those who do have one." If you know who you are, you will know what to do, and you will no longer be at the mercy of other people telling you what to do.
