Form me online poker is completely different from live poker. I read people very well and is a big factor in my live poker. The more somone gets me fooled the the more I want to study this person. Body language is a non verbal way of communication, different people react differently to any given stressful situation. Online you don't get any of that. So it feels more like a job for me to force myself to pay attention and get the feel of what kind of mental state everyone is at the table. All that based usualy on a time of response.
When i watch a movie and play I quickly get more interested on what's going on in a movie then what's going on at the table. Music gets me in the flow state quickly, online and live. When i put headphones on, nothingness arives and I just analyse everything I see. Body and mind work better like this. Down side of this? I can't do this for more then couple of hours. Sometimes I put something on a tv with no sound, just so I see something moving at all times. Usually a movie I have already seen. We humans are very visually oriented animals use it to your advantage.
