When our ancestors first saw fire, the first things they saw and understood were destruction and danger. As time passed, as they became more thoughtful and more adventuresome, our ancestors learned the energy of fire could be harnessed and put to productive use.
Harnessing energy and putting it to good use...that's the territory of leadership.
So, when you see people blowing off steam at work recognize there is energy generating the steam. Energy is good. Energy does good when it is harnessed and properly directed. That's a thing of leadership.
