Here is a nice article on being likable.  This is such an underappreciated characteristic.  The author makes the point, “If you’re disliked, it may not matter how competent you are, people simply won’t want to work with you.”

Likability reminds me of Guy Kawasaki’s recent book on Enchantment.  In it he provides his own advice on likability.

Kawasaki’s are more practical but both authors provide good food for thought.
