Happiness is very important in life.
Why is it difficult to define?
What factors are important for achieving happiness?

It is clear that happiness is the thing people always want to pursue and try their best by all means to achieve . However, it is very hard to define happiness fully and each person seems to have his own definition. In this essay I am concerned about importance of happiness, difficulties in defining it and factors for happiness achievement.

Firstly, in my opinion , happiness is emotions and feelings that you have when our material and spiritual demands are satisfied. Happiness is very important to life because it make life meaningful. It is hope of a happy life that people work hard for learning money and create new values to improve their living conditions. It's desire of happiness that soldiers are devoted their lives to fight against enemies and protect peace of their countries. It's happiness that promote human beings to use their minds and hands for discovering new things and creating such a modern society .

Secondly, the main reason for difficulties in defining happiness is that each individual has different demands and the degree of satisfaction varies in each person. For example, when a businessman can exploit intellectual ablilities, physical strength and necessary skills to fulfill his goals in career, he will be successful. His ablilites are recognized and appreciated. He has a comfortable life with a big house , a good car, a beautiful wife and lovely children. He feels satisfied with his life and we can say that he achieve happiness. However, even a fisherman who has to work hard everyday in the sea can achieve happiness. He loves his job ,feels pleased with his daily work results and has sound sleep at night. We can also say that he 's a happy man. Sometimes, happiness is very simple such as a kiss from a lover, a hug from friends, a smile from a stranger or a comfort from natural beauty.

Thirdly, happiness seems to depend on many factors. Happiness will surely come to people who know what they want clearly and how to get it exactly. Therefore, hard work and non-stop study ,optimistic viewpoints and positive attitudes will be happiness's basis. In fact, some successful people still not feel happy because they are not satisfied with themselves. It is good that a person isn't pleased wit h his present and want to improve his life, however, he had better hold tightly what he has and try his best in the future.

In conclusion, happiness make a beautiful and colorful life.If we have clear plans ,be ready to face up with difficulties, work hard and respect our results, we will achieve happiness.
Dear Thuthu87,

Look what I found!

I ran a few of your sentences through Google and found almost the exact same text written by someone else on September 8, 2011. /

This is called plagiarism. Do you know what that word means? It means "taking someone else's work or ideas and passing them off as one's own." We also call it "cheating."

Do you know what "cheating" means?

Do you know that I am the author of the writing Happiness in essay forum? although a friend of mine has checked it, I do not sastisfied with the corrections. That's why I post the writing here. Can you susgest anything to make it better? thank you in advance!

No, I did not know that you were the author because you used two different names and posted on two different dates on two different sites.

If anyone did the same thing as I did in checking Google, they would have reason to suspect that two different people wrote the same text.

This is extremely dangerous for you and I can only suggest that you use one name - the same name - when posting on forums where Google spiders pick up every word!

Plagiarism is an extremely sensitive topic in higher education and many students have been refused admission and have even been expelled because of it.

Best of luck in your endeavours.

Dear John,

I catch your point. You have your own reasons to think that I copied the others' work. If I were you, I would do the same. In essay forum my username is beepro21 with my full name"dinh thi thu" under each thread and my username is thuthu87 in this forum. I think two names are related to each other and maybe people can guess that two names refer tothe same person. However, you help me realize that it's not what others think. Anyway, can you help me check my writing ? You are not only a native speaker but you also an English teacher so you can give me good advice. Please check my essay and give me some comments and corrections.

Best wishes,
