It is believed that focusing on a singe career is out of date these days. The new trend is that people should have more than one occupation in their life, and they should never stop learning. Personally, I agree with the new trend, as it has more advantages.
In the old days, people were loyal to their company, focused on their occupation and stayed there until they retired. However, some people believe that a competition in labor market at that time must have been lower. People did not necessarily own more occupation. But these days, having several occupation is precious asset, since people could bring innovative idea from their previous company and implement it in the current workplace.
Furthermore, it is undeniable that continuous education is an essential thing these days. People need to update with the current condition since economy, information technology and science develop rapidly. Those who are not following the latest information and regulations will face difficulties in their careers. For instance, people who work in the information technology sector should update themselves with the latest type of software, since information technology is rapidly developing. Those who fail to update will face serious problems in the workplace.
In conclusion, I personally believe that having different types of works in life is a positive thing and bring a lot of benefits to person's career, and it is important for people to study or learn throughout their life as the world never stop to develop.
