Have fun in the process...embrace it. Just keep in mind, a degree from The Ohio State University carries a ton of weight. We also have one of the largest Alumni Associations in the world, which can be helpful for that "40 year plan" you referred to.
As an alumnus of a large Jesuit high school a little south of you in Cincinnati and a graduate of Ohio State (couldn't go to Notre Dame...they did not have a Pharmacy School) I can assure you I made a good decision. My father was right (again) when he told me as a senior not to worry about making the right decision. "You make the decision...then YOU make it right...anything else is the tail wagging the dog and I didn't send you to St. X to be a follower."
Pretty good advice to a 17 year old kid who couldn't find his rear end with both hands. Think about it and best of luck to you.
