Just listening will usually help those who already know they have a problem and for those who don't they won't benefit from your wisdom until they feel like you heard them and understand their problem. Sometimes people can figure out their own problems as they talk about it. It helps them to sort out the facts as they explain it to you. There is a time for words of wisdom and then there are times when it is wise to be silent. Lending an ear may be all they need. Silent words of wisdom sometimes speaks volumes.
