Cognitive neuroscients believe that one can use training exercises for a keener attentional focus, a way of building concentration. Meditation methods can be used to build concentration. The cardinal rule of all concentration enhancement techniques is to focus on something specific and whenever your mind wanders off to a different topic, bring your wandering mind back to your initial focus. Every time you do this you are enhancing the muscle of concentration and attention. (Goleman, Daniel Jay, PhD. The Brain and Emotional Intelligence: New Insights. p 50-52. MA:More Than Sound, 2011)
