There is a new trend in coaching set up by the Inquiry Institute (inquiryinstitute.com).
Coaches usually say, "We have questions, you have answers."
In this new trend instead of a coach asking expert questions, client himself finds his own best questions and, of course, his answers, and the Inquiry Coach facilitates the process.
It is called Q-Storming, or finding your own best questions to help you succeed.
I used to do a similar thing with few of my clients.
Before a session I would ask them what questions they want me to ask them in a session and they would email them to me in advance.
In a session I would ask those questions, and some sub-questions if needed, which would help them think deeply about their issues.
These were some of the best coaching sessions I had.
