WIIFM

I'm sure you would have heard of Hits FM or Fly FM. They are radio network station. WIIFM is not anything of that sort by the way. It stands for What's In It For Me.
I realize some people's mind is just tuned in to WIIFM. Everything you say or do with them but be centered to them otherwise the discussion is just not meaningful. They must see how they can benefit, primary monetarily.
I don't know about you but I just don't enjoy talking to them however if you don't have a choice, here are 3 ways to do it.
1. Choose not to talk to them even if you have something fun that you want to share with them. This way you keep the respect going in them.
2. Set the tone during the conversation with them by asking questions and go less by answering their questions.
3. Match their tone of voice when talking to them. Be sensitive with their rhythm and pace of voice and follow them but make sure they don't know you are consciously doing it. Matching them may make them be comfortable with you.
