For those who do not have any prior training in meditation or some other means to clear your mind, like a good exercise routine, when you are not trading, this is a good introduction to very basic meditation.
The technique explained in the video is not complex at all. All it takes is your willingness to give it a try and practice it everyday. Similar to any other mind training techniques, it takes time to do this proficiently.
For those of you who already know how to do meditation but having difficulty in maintaining your meditative state for prolonged period of time, the concept introduced in the video can help you improve your speed in entering the meditative state which in turn compensate for the time you lose during a meditation session.
