Music is a fun and satisfying industry to be in, but it can also be frustrating.
The people that I know who have made it into the industry started at community college studying Music Technology at Shoreline Community College in Seattle (https://www.shoreline.edu/programs/music-technology/default.aspx). It's cheap and a fantastic program for learning all about music production.
Studying Music Technology or Audio Engineering while also studying music can be a good route, as it is easier to find a paying job as an Audio Technician or Sound Engineer than as a Musician. You can then work in the industry as a tech while you write music, study music, or pursue music as a career.
Overall I would say that you should do what makes you happy, but I would also recommend keeping in mind that you will want to make a living as well. Studying Music Technology is a way to do both (if music is the career path you want to pursue).
I hope this helps!
If you would like to develop your careers in Music, you can take Music as your major in the college. Then, you can develop your career in music industry, e.g. song writer, musician, production, music teacher, etc.
Similarly, if you would like to develop your career in Sports, you can take Sports as your major in the college. Then, you can think about to be sports player, sports journalist, coach, sports teacher, etc.
You can explore more online how these careers works and which one you are interested in. Hence, you can further develop in that career.
Hope this helps! Good Luck!
College classes, volunteering, joining meet-up groups are a great way of finding out what you like and don't like.
For example, by trying different things you may fall in love with something specific, like an instrument under the music umbrella or like a specific activity under the sports umbrella.
It's hard to pick between two things, and a career path CAN be changed, but it can often end up being something we do for the rest of our lives. So, why not do something we love doing?
Wishing you the best of luck in finding the right fit for you. If it makes you feel any better. Most people don't REALLY know what they want to do after high school, and many aren't even 100% after college.
