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.

A Christian people who have for two hundred years kept a race in bondage, deprived of the advantages of civilization and religion, owe them a debt of gratitude which it would seem ungenerous to withhold.

People have this idea that the more pious and devout I am, the more successful I am. Which is very dangerous. If you look at faith in that way, you're bound to fail at both - spiritually and in your career.
