Does difficult jobs make people much happier?

Admittedly, there is no denying that the challenge of challenging a difficult job can give people a sense of achievement, especially when we refer to those experienced people, who have been worked in their field for a long time. By dealing with a hard work, not only can these people get a sense of success, but also they can also learn how to conquer difficulties from troubles. One illustrative example being my uncle John, he is an experienced chemist in our university. He loves chemistry so much and he always tries try to lead challenging and difficult projects in compounds labeling. Although most of these projects are costly and hard to achieve conquer, he and his teammates always work so hard and finally solve these problems. Having completed this research these researches, not only can he win more research funding (if you are talking about money) investment, but also he can also accumulate more knowledge about that research. It is challenging difficult jobs all the time that gives these experienced people more chance to win.

However, plausible as above the scenario may seem, it is still irrational to overstate its significance because difficult jobs can also make people feel frustrated, especially not least when we focus center on those beginners freshman. People who have little knowledge about a one field will surely be sad when they encounter a challenging job in that field. If one people are compelled to take a difficult job, they will lose their confidence and interest when they fail to complete it. For example, my little cousin is seven years old. He liked music very much in the past, until one day his father forced compelled him to play piano. It is so hard for a seven years old boy to play piano well. Soon, my cousin lost his interest in music. Thus, from this point of view, it is not a good idea to compel beginners freshman to take hard works.
