Some kids know exactly want to be when they "grow up", but others, like me, feel very overwhelmed when it comes to choosing a life-long profession. My sincere advice is to explore options as much as you can, even if you have to take a gap year to do so.

I say this because I rushed into choosing a subject, which I eventually graduated in, but never used. I enjoyed studying it, but applying it, well that's a whole different story.

Very good and important advice @alvinauh
