As i work with many leaders in development, there is one thing that trips up more people than any other factor - and with each passing year, I see more and more of it.

I call it FABJ - Fear, Anger, Bitterness, and Jealousy - but these things are all byproducts of one thing.  Feeling not good enough.  We all suffer from these feelings, but if you are a leader....you have to learn how to handle or manage them.
