Focus on your aim
One day Swami Vivekananda was walking somewhere. He saw some boys who were shooting sailing eggs in river. No one was able to shoot on right egg. Then he took a gun from one boy's hand and started shooting. In the first attempt, he got success. After that he shot towel time in an interval. The shot was gone on right places by Swami Vivekananda. Seeing that all boys has shocked and they asked to Vivekananda. How have you done this.
Swami Ji spoke. Whatever you are doing, you should focus in your mind on that. If you are shooting, you should keep your mind on that aim only. Then you will get success. If you are leering your lesion, think about only lesion. In our century, all the children are taught that lesion.
