" Most schools don’t do this job well at all. Instead, most children feel failure when they go to class. They could also hire athletics to do the job. For a few, sports do the job well. But for the less gifted, athletics makes students feel failure, too. So they hire electronic games to feel successful. And yet for many, even such games yield failure. So they hire friends who have feelings of failure, too—and engage in drugs and other things to feel successful. "
