"The persistent are attached to the goal. The obstinate are attached to their ideas about how to reach it. Worse still, that means they'll tend to be attached to their first ideas..."

So obstinate people expect the desired outcome to depend on their expertise at some point(s) in the past. Is the difference between the two just humility?

Some do that humility was the mother of all virtues in the same way that pride is the mother of all vices ... I don't have any data to back it up either way, but I would say anecdotally (and thus providing a single datum), "yes".
