However, there is a huge difference between the two. Pleasure is a goal. Happiness is a by-product. Pleasure is fleeting. It ultimately leaves one empty.
Happiness is lasting and can leave one fulfilled.
Happiness results from a project well accomplished, a good deed done, a love freely given. Ignoring our conscience may bring temporary pleasure. But it will not bring happiness. For example, Henry Cisneros might have gained fleeting pleasure from his affair with Linda Medlar Jones. But he was denied lasting happiness.
