This is a slight variation of the "Fruity technique" given above. In this case, pick up a small object such as pen, pencil or paper clip and look at it, concentrating hard. But do not think about it. Just keep looking at the object without thinking anything about it. It may be a bit tough in the beginning, but you will improve with time. Keep doing again and again and it will work wonders to the level of concentration.

Please refer to the book for more details on this activity.
