As modern society develops, people have to possess more skills to deal with more problems brought by the heavy load of work. However, the rapid changing speed of the work environment among us can never be ignored. The ability to adapt new environment means a lot to one's success. Even though some believe that outstanding knowledge for a job is of the most importance, from my own perspective, the adaption ability plays the most significant role in one's career life.     First, people all over the word affected enormously from the rapid change of society, as well as the environment among us. Life abounds with such example. With the development of science and technology, an increasing number of people begin to work online, searching internet become the most convenient way to acquire knowledge and get information.  However, my friend Tom cannot adapt to this change. He still stick to the tradition way: he goes to the library to find the information and search the useful data. Though he spends lots of time in the library, it is hard for him to find the available information and the data are always run out of date. Whereas, with the help of internet, we can acquire these useful and latest information or data in a few minutes . Without any doubt, the ability to adapt to the new working environment is of considerable important .    Second, sometimes we have to go to work in different places, for example, last year I was sent to work abroad.  My working and living environments changed thoroughly. The people there always work to midnight and love spice foods which I can hardly adapt to these custom. My working efficiency declined rapidly. I tried my best to get used to the working hours and the eating habits and my efficiency raised remarkably.     However, the outstanding knowledge for a job is also a vital ingredient of career success. Without the excellent knowledge, we can hardly find a job and it help to lift us to a new height.    According to all these reasons above, though excellent knowledge for a job can never be ignored to contribute to a successful carer, I strongly convince that the ability to adapt to a novel environment is the most important factor leading to the final success.
