Most young people in high school and beyond do not know what career they want to pursue. Actually many people start a career and decide it is not the right path for them so they change. My advice to you is to think about what you are passionate about and what are your strengths. Are you good at math or science, are you artistic, are you a people person, etc.. Then i would suggest trying to talk to people who may have careers aligned to your interests to gain some insight of what they actually do in their jobs and ask them what they like and also dont like about their careers.
If you are going to pursue college, and not sure what major you want, you can begin with undecided and see what interests you.
If you decide to college-- take general classes and see what subject areas resonate with you. In the end, if you are still unsure, you can focus on degrees that are useful across multiple paths: business, psychology, or any area that allows you to develop critical thinking skills.
If you decide not to go to college, reflect on what makes you happy and your passions. Then look at relevant activities to make you an expert in that area and grow into that space.
I simply want to offer the advice I would give my younger self, when I asked this same question.
The answer to “what is right?” is always going to be inside you. So solicit as much advice as you think you want, and then find the voice in your gut, and follow whatever delights YOU the most.
