We do not want joy and anger to neutralize each other and produce a surly contentment; we want a fiercer delight and a fiercer discontent. We have to feel the universe at once as an ogre's castle, to be stormed, and yet as our own cottage, to which we can return to at evening.
Joy is the wild card of life; it supersedes every other formula for success. If you can find a way to create joy, you can rise beyond all external factors. If you can play at whatever you are doing, you are the master of your life.
If there ever was a pursuit which stultified itself by its very conditions, it is the pursuit of pleasure as the all-sufficing end of life. Happiness cannot come to any man capable of enjoying true happiness unless it comes as the sequel to duty well and honestly done. To do that duty you need to have more than one trait. From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.
Instead of answering your question directly I shall quote from the Indian poet Tagore: “I slept and dreamt that life was joy/ I awoke and saw that life was service/I acted and behold, service was joy.” In fact, through my work I discover life, people, and everything which happens around us.
Service which is rendered without joy helps neither the servant nor the served. But all other pleasures and possessions pale into nothingness before service which is rendered in a spirit of joy.
He knew she was there by the joy and terror that took possession of his heart [...] Everything was lit up by her. She was the smile that brightened everything around.
