Have something really important to say to software team leaders out there? Why not publish it in my upcmoing book? It could be anything, as long as there is a PERSONAL story in it.
Outline why you liked/disliked that team leader's behavior. Explain how things could have been better, or worse.
If it's about you, and a lesson you've learned about being a team leader - tell it, so others can learn from your experience!
