What does "work smarter" mean operationally? If there were a little switch you could throw in your head, we wouldn't need the Overcoming Bias blog.
It takes an effort for me to step back and ask myself what the problem is, rather than just sitting down and working on it.
Usually "just sitting down and working on it" works, which may mean my problems are too easy. :)
But you'll notice that it takes something more specific than "work smarter" to change up the way you approach a problem.
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.
I think trying to reduce this post to one sentence is probably a bad idea anyways. I thought it was worthwhile reading.
Work smarter and harder.
Couldn't you, in your head, convince yourself that you are working "harder", simply by imagining that you could work less hard than you currently are? Couldn't you do that, regardless of you current level of work? So does "work harder" even mean anything?[1] http://www.overcomingbias.com/2008/10/trying-to-try.html
