Some people tend to stick to their positions all the time, as they think the longer one works in a particular field, the more skillful one will be at it. Some have been teachers all their lives. Some devote their life energy to scientific research. Such people love their work and turn out to be specialists in their own field. They are usually high achievers. Some are different. They are in the habit of job-hopping, for they always pursue what is new and stimulating. They never seem content with their present situation. Some like to meet more people, make more money and new acquaintances, so they hop from job to job. As far as I am concerned, I want to be professionally strong. I am not in favor of frequent job hopping, as the saying goes "Jack of all trades, master of none". But I want to have opportunities for advancement and as many colleagues as possible to cooperate and communicate with so as to be more creative and less partial.
