Overview
Even if you know the solution to someone's problem today, be careful about how you offer your advice. Be sensitive, and try not to come across as a know-it-all. Getting up on a soapbox is just going to make this person defensive. Instead, guide him or her to the answer with questions -- for instance, you might ask, 'What would you tell me if I had this problem?' Empathy is a wonderful tool for learning how to make better decisions.
