I was really pleased to read this article, on many occasions I have been faced with a development project where the distance between the as is and desired destination is much further than the participants think, often for good reasons but sometimes due to arrogance - the latter being much more difficult to manage. 

The shame is that it takes a very confident person to admit they don't know something, very few companies create an environment where employees and certainly senior exec's are even given the time and space for personal development.

An american philosopher called Nicholas Butler said "An expert is one who knows more and more about less and less until he knows absolutely everything about nothing" which seems quite apt in this situation. 

Personal and professional development is more than just updating necessary qualifications or brushing up on leadership skills, it is also about keeping relevant, energised and focused.

Great article.
