Are you getting feedback on a regular basis as a leader?  If you are a CEO, is your senior leadership team comfortable giving you feedback?  Are you getting feedback from your board?  How are you handling it?

What does it feel like when you get negative feedback?  For me, sometimes I can get defensive.  It can depend on the subject, and on my own emotional state and level of stress at the time, but more often than not my tendency is to be defensive.
