阅读下面的短文,并根据短文后的要求答题(请注意问题后的字数要求)。

[1] Many people spend a lot of time making money because they believe the money itself will make them happy, or will guard them against things that will make them unhappy. They make great efforts to achieve that perfect relationship, the perfect house, the beautiful body, the approval of others, all in an attempt to be happy.

[2] Sometimes these things make people happy; other times, people stress over not having reached the goals, or reach them and find they’re still unhappy. Other times, people focus on just one goal and don’t have time for other things that will make them truly happy.

[3] Some experts studying human happiness and the factors that contribute to it have identified several key areas of life that seem to be more related to personal happiness. Some of them are the things like money, friends, health and living conditions; others are things you may not think of in your daily life, such as your neighborhood and sense of meaning in life.

[4] So while setting your goals, remember all of the areas of life that are important to you and find a balanced lifestyle including social support, personal development, physical health and meaningful pursuits(追求) besides career success and financial security. _____________, your attitude about life and the things that happen to you each day can also have a great effect on your level of happiness and life satisfaction. In addition to being optimistic, happy people tend to believe they are the masters of their fate, rather than the victims of circumstance.

[5] Explore the state of your life, assess how truly happy you are, and find a direction to work toward that will likely bring more happiness. Reach your goals, set new ones and live a life that truly makes you happy.
