Interesting post by Guy Kawasaki on ego and how much it costs companies.
Ego is such a strong political force within the office. Although it seems like the cost of ego within an office correlates strongly with the level of the person who is egotistical. Ego in a manager makes underlings waste time creating ways to accomplish goals without hurting their manager's ego.
I wonder if young professionals feel it to a greater extent because we're at the low-end of the totem pole and have a larger number of people where ego must be dealt with.
