The preferred form of the adjective meaning tending to make use of selfishly (exploit) is exploitative, not exploitive. This grammatical error needled me every time I came across it in the book, which was often.
I may have read too many of these self-help books now, I'm losing patience with them. This one is heavy on questionnaires and form-filling.
One thing I found of use from this book was the recognition that I do have PTSD, or at least a sign of it: I dread the phrase"can I have a word?"
For no reason, I freeze, panic, and assume I'm in some terrible trouble. I now realise this is because it was a favoured tactic of abusive bosses: to get me into their office, with a closed door, and then subject me to quite horrible & personal shouted abuse, on the pretext of "having a word". These meetings weren't constructive, they weren't designed to improve my performance, they were used to humiliate me and batter me into being submissive to the abuser.
To this day, 15 years after the last episode, I still have that terrible, stomach-dropping feeling of being in awful trouble if somebody says "can I just have a word with you?". I feel like a naughty child again, even though I'm more than middle-aged now.
