"A good listener is not only popular everywhere, but after a while he knows something." Wilson Mizner
Friendly - practice smiling by thinking about something you enjoy.
Talkative - focus on asking good questions.
Communicative - consider who you are talking to and what they are asking for. Real communication isn't what's said, it's what is understood, so you need to ask questions to make sure you were understood.
Funny - "The ability to quote is a serviceable substitute for wit." Somerset Maugham (It works for me).
