Excellent points Geoff.  Thanks for weighing in and adding the background for your tweet.

Totally with you that leadership is required at all "levels" to achieve success in any endeavor, especially in business.

Although I agree with your point that management is a specific skill, I don't think it is limited in application internally to a business.  My mom managed our household like a finely tuned machine when I was growing up!

Love this point in particular - management without leadership does stifle people, but leadership without management can lead to chaos.

Also, would you please post a link to the blog post you reference in your comment? I would like to read it and am sure others will too.  Thanks!
