Hi, Marimia,
So appreciate for your help. Welcome to China!

Below is the re-writed essay, pls check again.

Changing your job frequently. Is it benefit?
When talking with one of my friends about how to promote oneself quickly, we found that there were two different ways to achieve it.
"I can do the same work in a company about one or two years, then I must change my job to get a higher position because of my advanced experiece". Different positions require different skills, one can always challenge himself during the working, he also can find the better approaches to complete his abilities more easily with some specific requirements. Every day is new so that he will keep his passion to face everything and be absorbed in solving new problems with some creative solutions, then proceed to another one with the feeling of success. If always doing the same work day by day, he maybe will lose his creativities and passion, and even to sink in some unnormal situations.
In contrast to that, one can and should do in a position much longer, so much so that he can get more detailed knowledges and skills to meet the requirements of some further positions. On the present position, he should do his job with thoughts of a higher position. If doing all work easily, He can go ahead to get a higher one with a better salaries and honors. By this way, he will not bear tough pressures, he will be happy to do everything with enough skills, and never lose heart when he fail to achieve his goals.
Comparing with those two ideas each other, we can find the advantage point is that they all want to improve themselves, but over time, the different ways will come equally to one point, promotion.

Thanks for your attention!
BTW:
1\ Can I use the short phrase which is highlighted above in the sentence? If can not, could you pls tell me some exact words?
2\I doubled space before each paragraphes, but it came to the first space when I posted it, maybe it is the problem of the website. Thanks for your reminding!
