I think people tend to generalize things. I, for example, have the mentality that if I understand\learn something with little effort, then others can do the same. The truth is, the others usually don't bother to put forth that little effort, which makes me the exception to the rule. For example, I recently made a decent chunk of money by creating a simple WordPress site that was valuable enough for my client...I would've paid a fraction of what my client paid if I was him. So I definitely concur with this post.
