Some false premises: That a B student shouldn't learn physics, mathematics and can't be an engineer (whether software or even electrical or mechanical engineering). That it isn't worth it for a B student to study the classics. That entrepreneurship is easier than hard sciences or engineering: from what I've seen, the skill-sets involved are orthogonal, and such a blanket statement can't be made.
