The Living Force
Well my first manager at IBM told me that the squeaky wheel gets the grease, implying I didn't squeak enough I guess, business politics is a pain. Will have to look at that thread.I don't know about you, for me learning assertiveness felt like I was being overly aggressive and maybe it had that appearance sometimes specifically when I was also feeling very reactive, but I cringed at the thought of being aggressive so often doubted my application of assertiveness. I'm not really sure what MBTI type I'd be classified as except I'm definitely introvert according to Susan Cain's description. In any case a councellor helped when he said assertiveness doesn't have to be loud and big. It can be handled quietly in the manner of Clint Eastwood.
Have you checked out the thread on boundaries?
