First, discover your personal egogram: your own unique personality blend of Critical Parent, Nurturing Parent, Adult, Free Child and Adaptive Child. Find out which of your ego states are OK - and how to change the ones that aren't.
Now, when you know your own personality strengths and weaknesses, you can match yourself against other players. Like the Marine Sergeant whose tough Critical Parent tries to dominate you ... Soft Sally whose Nurturing Parent gives you more than you ask ... the Perfect Employee whose Adult keeps everything under control ... the Thrill Seeker whose Free Child calls the shots ... or the Wallflower whose Adaptive Child is afraid to be wrong.
Egograms. The positive TA approach to understanding your ego. And recognising the egos you're up against.
