I hate making mistakes. As I've aged I've learned that making mistakes is part of the process. It is the place where I learn the most. What I hate more is not learning from previous mistakes and making the mistake twice. Doh! Although much more difficult for me but altogether more effective is if I can avoid making the mistake myself and learn from those of others.
With President Obama taking over from George W Bush, I would say there is a ripe harvest of lessons learned and examples of what not to do. Bob Woodward over at The Washington Post has kindly given President Obama a generous gift by identifying those costly mistakes and giving him a robust instruction on how they might best be avoided.
As I read through the list, I thought to myself, hey this doesn't just apply to the presidency or the leadership of a country. Any leader in any position could (without too much effort) translate these to make them applicable in their role.
Read and learn.
