Have an Answer?
Choosing what to do as a career path can be very troubling but you don't need to panic. In the early stages of our professional life is hard to commit to something right away. You may try to explore different options in between an area.
To help you start I would suggest to answer to yourself some questions.
What of your different subjects did you enjoy the most ?
Who has been you favorite professor/ teacher and what did they teach?
You will know you have the right fit when you find yourself talking about what you do often and trying to share it with the ones you love.
Go ask, try and when you find that the time flies while you are doing it ... well that is your answer.
