A pleasant state of mind

Happiness can be described as a positive(實在的事物, 確定的) mood and a pleasant state of mind.
A good education and income are usually considered necessary for happiness. But the rich are not sure to be happier than the middle-income group or even those with very low incomes. People with a college education are somewhat(稍微) happier than those who did not graduate from high school; It is believed that this mainly because they have more opportunities to control their lives. Yet people without a college education may be less happy than those with a college education. Moreover, having good health can be very important to people because they can feel happy and have energy to do what they would like to do. Nevertheless(然而), poor health does not rule out(排除) happiness except for the dying or those in great pain. It should be noted that people quickly get used to what they have, and they are happier when they feel they are increasing their level no matter how little it has been improved.

幸福可以說是實實在在的心情、愉快的心境。良好的教育和收入對于幸福來說通常認為是必要的。但富人不一定比中等收入群體或甚至是那些低收入的人更幸福。有著良好教育的人稍微要比那些高中沒畢業的人要幸福點。相信這主要是因為他們有更多的機會去掌控他們的生活。然而沒有大學教育的人可能沒有那些擁有大學教育的人幸福。此外，對人們來說擁有良好的健康是非常重要的，因為他們會感到快樂而且有能量去做他們想做的事。然而，身體不健康并不會排擠幸福，除了那些將死的或承受著巨大痛苦的人。應該指出的是，人們很快就習慣他們所擁有的，當他們覺得他們的水平有所提高時，不管是多么微小的提高，他們都會更開心。

 The best formula(客套話) for happiness is to be able to develop the ability to tolerate(寬恕) frustration(挫敗), to have a personal involvement(纏繞) and commitment(承諾), and to develop self-confidence and self-esteem(尊重).

對于幸福最客觀的說法是能夠有承受挫折的能力，能夠親身體驗，遵守承諾，有自信和自尊。
