People would be much happier if they are doing different types of tasks during their workday than doing the same task.

　　With the rapid shifts of metropolises, the importance of happiness has been increasingly emphasized by the public. When people are commenting whether workers would be much happier if they are doing different types of tasks during their workday than doing the same task or not, people's opinions are diverse. With my careful consideration, I personally consent to the perspective that workers would be much happier if they are doing different types of tasks during their workday than doing the same task. My thesis could be circumstantiated by the following two reasons. Firstly, doing different types of tasks can help people gain more knowledge to be happier. Secondly, doing different types of tasks can increase working efficiency to make people happier.
　　Firstly, taking the advantage of dealing with various kinds of tasks, people can easily learn diverse aspects of lore, which capacitates them to be contented. As we all know, people can be more confident and earn more respect when they feel that they are more knowledgeable than others. In fact, people who possess more knowledge could gain a more trustworthy impression to others. Because of that, doing multiple types of tasks can help them to earn more prestige to increase the degree of happiness. For example, while my friend Sherlock teaches three subjects in a university, obtaining a bright mood every day after gaining more knowledge than other colleagues who major in one subject, my colleague Mycroft always becomes gloomy dealing with the routine work of being an officer. As a result, Sherlock is optimistic for his daily work, but Mycroft is not willing to work and finally left his position. In conclusion, it is necessary to do different types of work to maintain a sanguine mood.
　　Secondly, without the interfering of being bored, people can accomplish the work using little time which can help them gain the sense of achievement and happiness. Engaging a single task could inevitably encounter the monotony of tediousness, which embosses the advantage of tasking on multiple jobs. When people doing plethora of tasks simultaneously, the body would reaction this pressure with dopamine secretion which is a substance for improving the level of excitement during the performance. That is to say, the more tasks that people are engaging in, the higher excitement that people would achieve, which becomes the cause of the hyper-status during work. For instance, while my cousin John Watson, dealing with all kinds of works for his own company, can complete the tasks in several hours because of the excitement of new challenges; his secretary Mr. Holmes, majoring in storing documents, spends several days finishing a simple publicizing document. In the end, John Watson gained great sense of achievements for his efficient work, however, Mr. Holmes is shame of himself for his terrible work. All in all, it is obvious that people can be happier by doing different types of tasks simultaneously.
　　With the content aforementioned, my thesis could be supported by two reasons which are learning more knowledge and increasing working efficiency. Thus, it is appropriate to draw the conclusion that both two reasons could make my thesis reasonable and well-supported. When people are commenting this issue, it is not supported to be forgotten what a famous Japanese claims” Difference creates happiness.”
