Yes, I understand it can seem callous. In this case, I honestly believe that my preferences are superior in the vast majority of instances (although demonstrably not all).
Not that dropping sports typically helped, based on other students. I was really paying for sports with my GPA; people who didn't play sports typically had better grades and about the same amount of sleep (the 2-3 hour average was pure homework; I didn't learn to study until college, largely because there simply wasn't time).
Athletic activities are experiences in their own right, that can be appreciated in and of the act and experience of the moment itself, rather than the assumption that all things must be a task so in order to establish some future goal.
