I remember as a teen, contemplating the international baccalaureate program at a local high school. I definitely had the chops for it, but I knew people in that program—it was intense.
It wasn’t the demands of the program that threw me; it was the all-consuming nature of it. For four years, you couldn’t do anything but be in the program. No extracurricular activities, no part-time job. No life. Even at the age of 15 or 16, having a life was important to me -- and not just in that "hanging out with friends" kind of way.
