The mind is like a muscle. And if you want it to be really powerful, you gotta work it out. Each new
fact gives you another choice. Each new idea builds another muscle and it's those muscles that are
gonna make you really strong. Those are your weapons and in this unsafe world, I want to arm you.
Okay, look. if at the end of the term, you're not faster, stronger, and smarter, you will have lost
nothing. But if you are, you'll be that much tougher to knock down.
