Great article Christina!!!  I would be quick to respond that although I've been a manager or a leader in various contexts for over 20 years, I find myself still making some of these mistakes!  Yikes!  Thanks for the reminders!

Another mistake I see happen with new leaders is the desire to make sweeping changes quickly, without taking the necessary time to inform, educate, enlist and inspire their team members.  New leaders have been "chomping at the bit" for so long for their chance to make a difference that they may lack the patience or maturity it takes to affect change in a purposeful but timely manner.

I know there are lots of other mistakes I've made too, but that's all I'm willing to confess at this point!  Thanks again for the reminders!
