Focus on getting your ratings, and find a way to work in the aviation industry as soon as you possibly can. Whether that's answering phones at the flight school, washing planes, etc, any early experience that lets you get your foot in the door somewhere will be invaluable. The connections you make and the networking you can accomplish will make your life WAY easier once it's time to get a more "serious" job, whether that be as a CFI, pilot, etc.
Concurrently I would recommend starting out at a community college while you work on your ratings, and then transfer to a 4-year program if you choose to seek a bachelor's degree right away. Remember, a college degree is nice, but not mandatory at the regional level (and I would NEVER advocate getting one with the word "aviation" in your major). Not saying you don't want a degree, but just saying it's not essential, and jumping straight from HS to 4-year college isn't the right timeline for everybody's situation. Bottom line is keep all your options open.
