If you were in your colleague's shoes, what would it be like?
This #question helps to see things from different perspectives (aka meta positions), and creates empathy thus opens your mind to different options and worldviews. You can replace <your colleague> with other significant people in your life e.g. mother, spouse, child, team or manager. Adding objects creates #creativity, lightness and fun e.g. your chair, your mouse or your underwear. Or you can also explore abstract words like #love, #compassion or #empathy.
Ask your client to move to a different place/chair, so there is also a physical shift in #perspectives. Explore the new place with all senses, so they are able to really go into it and associate with “being" there:
What am I feeling? or How am I feeling?
What am I hearing / seeing / smelling / sensing?
What am I thinking?
What do I want?
Usually major “Aha” moments happen when someone is able to shift their #perspectives. Get prepared for tears and lots of tissues.

When to use
When someone is stuck and not able to see someone else's point of view
When a client blames others
When developing emotional & social intelligence, expanding #self #awareness and greater empathy is needed
When you want to explore #unconscious #bias
