The Sense of Achievement (revised)

Everyone has different goals to struggle for. In our daily lives, workers in various fields strive and students study hard. It seems an unchangeable routine. What do they actually struggle for? The former ones work not only to support families but also to gain respect and win applause, the latter ones want to get good grades because not only their parents ask them to do so but also students themselves want to win admiration. Therefore, the sense of achievement plays important role in driving people to achieve their goals.
Yet what is the sense of achievement? People will feel happy and proud of themselves after struggling for their goals, going through setbacks and finally achieving what they desire for. To me, that is the sense of achievement. They will get applause, admiration, and respect. And those are the rewards of their efforts. They enjoy in the atmosphere because the taste of the sense of achievement is sweet, just like the proverb says"sweetness comes after the bitterness." As for me, during my life of almost 20 year-old, I also get a lot of sense of achievement.
When I was a senior high school student, I studied harder than others in order to good grades. I enrolled in a good college. I felt superior to others because I did well on tests. The sense of achievement was not easy to get because contrary to others, I spent much more time on studies, not entertainment. Except studies, I also had different kinds of sense of achievement, including the first time I was the class leader in senior high, hosted the evening party of the club, worked as the executive of a drama,etc.
I learned many things such as how to copy with things,and how to arrange things in better ways. Being a class leader, I announced and posted important information to the classmates, and was in charge of the fairs of the class; being the host of the evening party, I needed to show myself up in front of the club members and react quickly. I gradually overcome my stage fright; last semester, as the executive of One-Act Play, I spent many days thinking ans arranged the process, checking and asking for suggestions. I encountered many difficulties and had to face much pressure. However, because of these experience, everything I conquered brought me the sense of achievement. The most valuable lesson I learned from are more important than the result.
The sense of achievement is like a stair. If you learn more experience and gain more sense of achievement from things, you will climb higher, and your horizon will become broader and broader. Put it simply, the sense of achievement is the content with one's own ability and performance. No matter how difficult and troublesome it is, if someday you finally finish it. The joy is beyond words. You will know everything you did before is worthy because the sense of achievement brings you the sweetness.
