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.
Swami Vivekananda
Always work hard. Intensity clarifies. It creates not only momentum, but also the pressure you need to feel either friction, or fulfillment.
