You can not possibly be a machine trading human if you are still a human that have emotions. There will be emotions at least. But all you have to do is be good and try to control your emotions.
Yeah right, were still humans it is very impossible to be emotionless, I think it is about having self control because if you dont control your emotions most of the time it will only lead to bad decisions and bigger problems. Based on what ive read here self control is the key to be successful in gambling, it maybe simple to hear but difficult to do, it needs a lot of work to achieve it.
