“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.” - Swami Vivekananda
Not only spiritual giants, I might add!
"We want that education, by which character is formed, strength of mind is increased, the intellect is expanded and by which one can stand on one's own feet" - Swami Vivekananda
Happy National Youth Day! Swami Vivekananda (12 Jan 1863 - 4 July 1902)
