An interesting read as always from raganwald, but I think the title is off. It seems to me that the reason Joel added "gets things done" to his creed was to avoid exactly these kinds of problems, and by "these kinds" I mean all the myriad ways that smart people shoot themselves in the foot by either overthinking, or making assumptions, or just plain being used to gliding through on minimal effort.
Now obviously the definition of "smart and gets things done" is open to a huge amount of interpretation, but I think it's clear enough that he means getting things done in terms of shipping useful product. If one does that, then the problems that come with inexperience are self-rectifying.
The problem is if someone is not "smart", they won't learn from their mistakes, and if someone doesn't "get things done" they may lose site of the final goal and fall into mental tarpits as they gain experience.
