What I Know For Sure

What do you know for sure? I know for sure that I agree with Rachel Maddow on Leadership:

Humans are ambitious and rational and proud. And we don't fall    in line with people who don't respect us and who we don't believe have our best interests at heart. We are willing to follow leaders, but only to the extent that we believe they call on our best, not our worst.   As told to Mamie Healey

Rachel Maddow is the host of The Rachel Maddow Show on MSNBC as well as her show on Air America Radio.
