Ultimately, the most meaningful act of responsibility that leaders can do is to control their own state of mind. Leaders who spread bad moods are simply bad for business - and those who pass along good moods help drive a business's success.
If you think your mood isn't making an impact on your workplace culture - think again.
What kind of Courageous Leader are you going to be today? Spreading a positive contagion or pulling yourself and the team down? It's your choice.
