'Take up one idea.Make that one idea your life--think of it, dream of it, live on that idea.....Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. ....This is the way to success, and this is the way great spiritual giants are produced. Others are mere talking machines.....To succeed, you must have tremendous perseverance, tremendous will "I will drink the ocean," says the persevering soul, "at my will mountains will crumble up."Have that sort of energy, that sort of will, work hard, and you will reach the goal. '
Swami Vivekanada
