Leaders are meant to lead change, and yet getting people to change their behaviour seems near impossible. How many times have you felt “If only *they* did what they were supposed to.” when faced with a peer or subordinate that wasn’t doing what you expected (or a child, or a spouse)?
Maybe it’s not them, maybe it’s you. Even if it isn’t you, if their behaviour or performance isn’t changing the way it needs to, maybe you need to change yours. After all, isn’t a definition of insanity doing the same thing over and over again, and expecting different results?
