I see. But wouldn't the task you give him have to do with your goals? Else, why would you send him on errands that would not have to do with what you want to accomplish? Unless members of his rank have to be distracted until allowed to work on that matter. And if the task he does have nothing to do with your goals, then his "help" is not really help, since it does not push the guild forward to its goals, but simply a way of keeping himself busy with something.
Or maybe he simply is not curious enough to question what he does, and therefore, even after acting to achieve "more organization, members, expanded activity within the clans and the quest for fame and glory" he does not keep track of it in his mind. May happen.
Or he is left with management duties, like providing, crafting, hunting or guarding. That would have been a good answer.
