above all have fun, poker isn't life or death. It's only a game.
I just can't agree with this for a beginner
As one gets experienced it becomes relatively easy to sit back, relax and chat away as you are comfortable with the dynamics of live play. When starting out it can be very overwhelming and ones play can suffer if one is too concerned with being social.
