Maybe toppers are successful in school or college carrier but backbenchers are successful in their life because toppers run according to books while backbenchers don’t follow rules and regulation that is why backbenchers are successful. For life, there are no books and another reason why toppers can’t succeed because they fear failure and don’t try anything new. Backbenchers don’t fear failure as they have faced the failure in their school or college carrier
