This seems to have worked for me. For the first part of high school I was a terrible student, then in one technical lab-based class with a lot of opportunity for student interaction, I started getting way better grades on the quizzes than everyone else, and earned the admiration of some of my peers for it. I thought "This feels kinda good," and next year (my last year of high school) I got straight As in all classes. And then I got more straight As through 4 years of undergrad.
