Swami Vivekananda

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, that is way great spiritual giants are produced.

Focusing your life solely on making a buck shows a poverty of ambition. It asks too little of yourself. And it will leave you unfulfilled.
