It’s ok -you’re 17. The guidance to go inexpensive is more important than ever. You might consider a business/entrepreneurship minor - or you can always pursue an MBA a couple years after you are out and working if that’s your long term goal.
It’s great you are planning - lots of paths to get where you want to be.
The only thing that will cripple you in your path is debt. You have a great future ahead of you otherwise.
