The advantage is yours. Take it.
By helping other people to prosper, you will bring prosperity and pleasure into your own life. What you do today may not bring immediate personal rewards or benefits, but the things you do today are likely to prosper for you in the near future. At this time, your good deeds are preparing the soil for a future harvest that will bring you greater abundance.
When you listen to other people, don't just listen for your chance to respond. Listen to what is being communicated. Otherwise, you might miss an important opportunity to hear what is really being said.
