Hmmm. The results of this poll and your comments, dela, have made me think about the subject of happiness more. I started keeping a happiness log, and, while it is too early to tell for sure, I have learned that I am happy a lot more than I originally thought. However, when moments of unhappiness come, they tend to overshadow and block out the happiness, the way a cloud can block out the infinitely more powerful rays of the sun.
I found out some interesting statistics courtesy of our wonderful Internet: "The average American is only 69 percent happy, and happy only 54 percent of the time (Seligman, 2002). Also, at any given time, one in every four Americans is suffering from mild depression (Seligman, 1994). While the happiness level of over one quarter of the American population falls between 57 and 71 percent, and 8 percent are even less than 57 percent happy, one fifth of Americans are over 85 percent happy."
