Quite so. I'm thinking that the whole lean startup movement in some ways exacerbates the schlep blindness problem PG refers to. If you expect instant rewards/feedback/traction before discarding an idea, you might sometimes be overlooking something.
[ no, no, meh, hmm, YESYESYES, hmm, meh, no, no]
The key to the Lean part is only doing a schlep when you've identified that it'll pay off once done. Don't schlep until you've got evidence that the destination will be worth the trip.
I see what you're saying. I just think that this leaves unresolved the one crucial question: what constitutes "evidence that the destination will be worth the trip?"
