Imagine that you wanted to drive a nail into a wall. Do you think you could do it? Sure you could; if you had the right tool. Now let's say: Because I like you, I believe in you and I really want you to succeed, I went out and, with great expense and careful thought, bought you a brand new, shiny red...chainsaw. And I tell you to go ahead and drive that nail into the wall.
"Okaaaaaaay," you're thinking to yourself. "He's successful, so I guess he must know what he's doing." And you start hacking away with your chainsaw, trying to drive the nail into the wall. A little while later, I come back to check on your progress.
