I try so hard, please help correcting my essay It is no doubt true that the majority of people desire to be happy (have a desire to be happy or desire for happiness) in their lives. The meaning of happiness is not fixed; instead, it systematically shifts over the course of one’s lifetime, so it is hard to accurately describe happiness. However, people can achive happiness with some main point. Happiness does not have a definite definition because it is an abtract concept which changes its meaning depending on personal feeling and awareness. For instance, in the eighteenth century, Vietnam is a backward country with most part of its population lacked of food thus Vietnamese people simply wished they could feed enough their children. By contrast, nowadays Vietnamese people feel fully fulfilled and content with different categories of needs such as healthy food, large house, good education for children, potential career,... In other word, it is imposible to explain happiness for all, but each person could define his own happiness by himself. Generally, two common needs that people should have to achieve satisfaction is being healthy and having a positive attitude. Firstly, people being a good health frequently meet better deals in lives rather than who suffer from disease. To be more precise, it is hard for people to be happy if they are illness. Secondly, people who have a positive attitude will live better than other do not. For example, when a student get a lose mark, he should find out what make him wrong and how to fix it rather than being upset and feeling disappoited. To conclude, happiness is hard to define because it is belong to how people feeling. I think that two main elements building the happiness is keeping healthy and positive attitude.
