I know it doesn't fall neatly into any of those categories, but I'd love some feedback on my idea:

I want to create an organization that is essentially a 6 week retreat for students before they begin college. Selecting the best applicants possible, they will go through rigorous training to become their most successful selves, covering Academics, Social life, Health, and Lifestyle topics. Elements of secrecy will help it's applicant pool, I was heavily inspired by the Bohemian Club.

Long term, the alumni network itself will more than make up for the cost, in turn making the applicant pool stronger and stronger.

It's an aggressive plan, and requires years of building up from the ground. But it's my dream to make it happen.
