Imagine that you are stuck.
You believe there is no way out or around a situation and you just keep bumping up again the same wall.
Now imagine that someone comes along and sits beside you. As you share your conundrum, this person quietly listens, reflects back to you what you are saying, what they are seeing and asks one or two questions.
Before you know it, you are able to see the situation from a completely different perspective and from that vantage point, you are able to develop a viable solution to get you out of stuck mode.
