Happiness can be described as a positive(实在的事物, 确定的) 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.

幸福可以说是实实在在的心情、愉快的心境。良好的教育和收入对于幸福来说通常认为是必要的。但富人不一定比中等收入群体或甚至是那些低收入的人更幸福。有着良好教育的人稍微要比那些高中没毕业的人要幸福点。相信这主要是因为他们有更多的机会去掌控他们的生活。然而没有大学教育的人可能没有那些拥有大学教育的人幸福。此外，对人们来说拥有良好的健康是非常重要的，因为他们会感到快乐而且有能量去做他们想做的事。然而，身体不健康并不会排挤幸福，除了那些将死的或承受着巨大痛苦的人。应该指出的是，人们很快就习惯他们所拥有的，当他们觉得他们的水平有所提高时，不管是多么微小的提高，他们都会更开心。

 The best formula(客套话) for happiness is to be able to develop the ability to tolerate(宽恕) frustration(挫败), to have a personal involvement(缠绕) and commitment(承诺), and to develop self-confidence and self-esteem(尊重).

对于幸福最客观的说法是能够有承受挫折的能力，能够亲身体验，遵守承诺，有自信和自尊。
