Thomas Stanley has not only found no correlation between success in school and an ability to accumulate wealth, he's actually found a negative correlation. 'It seems that school-related evaluations are poor predictors of economic success,' Stanley concluded. What did predict success was a willingness to take risks. Yet the success-failure standards of most schools penalized risk takers. Most educational systems reward those who play it safe. As a result, those who do well in school find it hard to take risks later on.
