These are the points that stood out for me; this isn't intended as a full summary of the Guide.
Key mentoring skills
I find the ideas of generative (Scharmer) and empathic (Covey) listeningintriguing, but almost too abstract to grasp (page 4)
Generative listening seems to be about the future. How can I simultaneously listen and anticipate a mentee's (another person's) future speech? Why should I?
Empathic listening involves both heart and mind. Can it still be non-judgmental?
Covey says empathic listening figures when there is high emotion, stress in a relationship, low trust, etc.- this chimes with plenty of other sources on assertiveness, dealing with conflict, etc. It's good.
Reflective thinking means slow down and be aware of your assumptions.
Reflective thinking is an important mentoring skill!
You have to be open-minded if you want to be a mentor: that's what reflective thinking does
Reflective questions(page 11)
plural forms signal there is more than one option
tentative language means ideas are open to interpretation
enabling language, for example "Given what you know about...."
empowering presuppositions, for example: "what goals do you have in mind?"
critical inquiry about a situation: a) what is true? b) what don't we know? c) what is impossible to know? d) what can we do to test our mental models? (page 24)
