text: Occasionally people have already gone through the exact same thing that is happening to you. This can make them wise, because they can use their past experiences to tell you what to do and what not to do. For example, when you need that push to do something you're scared of they can help you with that. When they tell you it went well for them, it helps you to follow in their footsteps. If there was a problem in their past experience they can warn you not to do that. One example might be that a girl dated this horrible guy who cheated on her, and she sees him with another girl so she talks to the the girl and warns the girl about what happened to her. Asking a person about their past experiences is one of the best ways to figure out what is right for you to decide.
