Aspergers ?
I'm diagnosed with Aspergers, a form of autism - which can make me exceptionally competent technically yet in (frequent) need of coaching regarding social behavior. Thus, I'm a Systems Analyst/Developer/Programmer and don't really aspire to management. While I'm not very reactive emotionally, I also may lack empathy and social skills to even understand what the heck 'EI' is... but I learned Assembler from the Manual and can learn nearly anything technical easily and design systems to be easily maintained and 'evolved' (by using existing components with layers of increasingly 'intelligent' and 'User Friendly' front and back ends), however I may get into trouble because I will also tend to say exactly what I mean (sometimes not politically advisable).
So whatever this 'EI' is (how is it measured ?) - I may need a manual.
Dianetics, Dale Carnagie, Toastmasters, etc. have been excellent learning tools - but I don't quite have a quantifiable grasp onto what 'EI' is or how to develop it.
