I am a Poor Communicator!!

Why is it so difficult to communicate? To be silent means a good communication? I am a poor communicator. I am too engrossed with getting my ways, forgetting that there are other people surrounding me. I am overly demanding. I always say not to expect so much from others but actually I am. It is only lips sevice. It is not right and I have to get away from this foolish act before things get out of hand. I am good at saying things but I have to be honest that I am so poor in delivering it. I expect changes but the only person that requires change is ME...
