Truly talented people understand that sometimes an organization isn't a good fit. Indeed, that sticking with them will do much more harm than good in the medium and long term.
You have to back your own ability. I'm sure Brands will have no problem doing just that.
Spot on. In public roles it's all about reputation management.
See Steve Walsh for example. Completely torpedoed his own career by overseeing a disaster and not managing his own reputation. Brands has done the same, but by staging his exit the way he has he'll bluff his way into another role.
