I once was engaged in an activity on a training day where everyone was asked to think of a little life problem that needed to be solved. Nothing major, just something like what to buy so and so for their birthday present or a little inconvenience that we needed to sort.
We than found a partner and sat directly opposite them. We took it in turns to have five minutes opposite our partner just talking about the 'problem' while she or he sat facing us actively listening. By actively listening, we meant giving good eye contact, nodding and saying things like 'yes' and 'go on'.
When we were asked to give feedback. Nearly everyone had solved their problem.
If there is a problem, the person with it has most authority over it. They have all the insider knowledge, are the most tuned into the problem and are the person that can work out the most-likely-to-work and palatable solution for their unique circumstances. So unless the problem needs the input of specialised knowledge, the problem owner is the best problem solver.
Funny because when someone comes to most people with a problem, they feel the need to offer a variety of solutions when the best thing they could do in most cases is probably be quiet and listen.
