"Another scenario comes to mind - death by a thousand small thinkers. Like the death of a thousand cuts, dealing with people over and over again - sometimes a rotating cast where a few may feature prominently. At issue is that you can barely get them out of their collective foxholes long enough to look around and see the big picture. An infernal small mindedness can drive a results oriented performer batty. No strategic thinkers in the lot, just a preservation focused self-interest, repeating what is to them their safe patterns. Very difficult to engage even when you draw the line for them for the connections of mutual benefit and complimentary missions.
Is there a solution? repeating the big picture like a mantra, finding new avenues to appeal, perhaps painting a picture of their impending doom from inaction and lack of course corrections. Just once of those days for me I guess."
