To help others， you don’t have to be an efficient expert in the art， and the main thing is the intention. You may be crude and clumsy， wasteful and ineffective， but if you sincerely try to help， your attempt produces nothing but good. The one you are trying to help knows your intention and is strengthened and encouraged by the magic of your sharing.
　　In nearly every case， your simple desire to help， converted into action， produces good result. But perhaps the greatest good is the good that you yourself get out of the attempt. Service to others delivers more joy to you than you deliver to them. In doing good， you free yourself into a clean world of joy and light. The good you simply try to do， regardless of the outcome， is always a success inside yourself.
　　Unselfish giving is your most efficient formula for happiness. You have embraced eternity instead of self； you have felt life， and you are now the world bigger than you were before you began the project.
