The best thing you can do is be really honest with yourself about the kinds of things you've done so far in life and how much you enjoyed doing them.
What that means is to take an inventory of activities that can encompass jobs, sports, classes, trips, or even pranks you played on friends. Of those activities, what gave you the greatest satisfaction? Which ones would you repeat or get deeper into given the opportunity to do so? Ditto for books you've read. Is there a pattern to your reading? Are there subjects that you are drawn to or capture your imagination? Look at your circle of friends. What do they have in common?
Tons of research have shown that people who do well in their careers have a passion for what they do. They are genuinely interested in their work. They look forward to the next day. Many of them are in endeavors that are unrelated to what they studied in college.
The key point here is to identify the kinds of things, now, that you are passionate about and use your education to develop your knowledge in those things. Don't worry about money or any of the other tangible rewards of the career. Focus on what brings you satisfaction, excitement, and the other intangibles. Your choice of college major will be wrong if it doesn't give you the preparation for the work you really love. And at your age, you may not be able to identify in detail the work you love, but trust me, the clues are already there.
