" We, however, have all kinds of different ideas about what happiness is. Some must go bungee jumping to experience a rush of joy, while others find bliss staying home. Some are happy in a concert hall, listening to classical music, while children on a playground could be music to the ears of others. Some people experience elation when they solve a complicated equation, while for others a cancelled math class is a happy childhood memory. "
