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.
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.
