I think what "work smarter and harder" misses the most is not the level of effort you need to make, but that in order to get to that level of "extraordinary effort" you need to take risks.
I think trying to reduce this post to one sentence is probably a bad idea anyways. I thought it was worthwhile reading.
I agree. (Incidentally, I wasn't trying to put down your comment specifically, in case it came across that way. I just replied to it since I didn't want to duplicate the point that working harder was also part of the equation.)
The idea of making an "extraordinary effort" compels you to define your efforts relative to what's "ordinary", pitting you against not only your own everyday level of effort, but also against the masses. "Work smarter and harder" doesn't.
Granted, the post could've been more concise.
