Don't think of it as dropping out, you're just getting your priorities in order.
You know what sucks? We'll tell you. Letting your mind wander off, thinking about some tasty surf as you stare out the window, only to be snapped back to reality by a pissed-off teacher. We'd suggest looking to the Billabong Men's Day Dreams Slim T-Shirt for the answers. We're pretty sure it's going to tell you to walk out of that classroom and head for the beach.
