It isn't a binary choice between "rockstar" and "mediocrity". There's a huge area between those two: "semi-rad".
That's the point. Learn to recognize when you've achieved a level of skill where you're qualified more than most, and don't have to double your effort and time to get to the pinnacle. The opportunity cost may not be worth it if you can otherwise spend it pursuing other interests.
Perhaps I just don't understand this semi rad thing. And yeah that makes a certain amount of sense. But it also seems dangerous in that it can easily be used as a justification for underachieving.
I suppose. But at the risk of getting a little meta here: Wouldn't that justification only be relied upon by underachievers in the first place? Anyone looking for a reason to not do more than they are is already in that category I think.
I take it as a "whoa, slow down" message to overachievers that are sacrificing a well-rounded life on the alter of excellence. Maybe they can do more by widening their focus a bit.
