In my opinion, the quote perfectly summarized not only the entire article, but the situations each of us often find ourselves in.

"Shit, I watched my Dad do this a million times why can't I do it now?"

"Wasn't I supposed to learn how to do this in college - where the heck was I that day?"

"I thought after learning how to do X, I'd know how to apply it to Y"

"I thought after listening to him, I'd be able to do this"

But, fair enough, I see your point (I should have added the above comment to my original posting); I'll try to elaborate more in the future.
