Show and Tell Time

Can you suggest a simple way to SHOW what coaching is when someone asks about it with genuine curiosity? Would you ask them to state a problem and then run thru the Model? Or, would you take their situation and teach them that their Thoughts create their Feelings and therefore they have a choice in how they want to think about it? I see these are both good choices. I’m looking for the way you  would handle it. Thanks so much! ; o )
