How can you truly find you passion/interest

Hi, I'm a high schooler who have plenty of free time and I want to use this time to try to find what I would want to do when I grow up. Right now, I feel like I don't really know what I truly like and want to do instead of soccer, which is a sport I played for a long time. So, how can I find or 'make the passion find' me?

I would like to know this for further insight on my college majors, jobs, and more.
