To love is to place our happiness in the happiness of another.
--G. Wilhelm Leibniz

To desire personal happiness is normal and healthy. Most of our plans, choices, and dreams about the present and future regarding jobs, relationships, and hoped-for achievements are geared to make us happy. It's never wrong to want happiness; however, to receive it at someone else's expense or to selfishly steal it from another will result in sorrow. And our greatest happiness will visit us when we least expect it - when we are attentively seeing to another's happiness.

Doing for others - perhaps shopping for a friend who is ill or aged, maybe offering child care to an overworked parent, or cooking a surprise meal for a lonely neighbor - will never fail to heighten our own pleasure.
