Most politicians have mastered the art (unfortunately) of saying a lot yet really not saying anything.
I notice that clearly frustrated journalists are more and more asking "Can you please give me a yes or no answer?" Still the politicians duck and weave and can't even say yes or no.
A good rule of thumb for real leaders is to do what politicians don't do.
Be open, transparent, authentic, candid. Your people will love you for it. Higher levels of engagement will be the result.
And when you don't know, say so. When leaders say "I don't know. What do you feel/think? relationships become more open and honest and of greater value and mutual reward.
Be the difference you want to see in the world.
