People work because they need money to live, What are some other reasons that people work?

It is said that the reason why most people work is because they need money to live. Of course, money is an important reason. However, in my mind there are many other reasons that people work for, such as sense of responsibility, self achievement, or just interest.

Firstly, a lot of people work for their responsibility. Soldirs work for the safety of the country, and teachers work for the growth of the next generation. My father is a very good example. He is a physician . He always tells me that he works for the patient. What makes him happy is not the high salary, but the recovery of the patient he treated.

In addition, many people work for self achievement. Those people usually have high salary and prestige. They don't need to work very hard to maintain a reputable life, but they still do that. Why? Because they have something want to accomplish. For example, my supervisor, a chair professor of my university, is an absolute "professor", working from 8:00 am to 11:00 pm everyday. Of course, he earns a very high salary, but in his eyes, achievement in scientific research is more important to his life. That's why he works so hard.

Moreover, some people just work because they like it. Jerrie is one of my best childhood friend. She planned to be a tourism guider when she was very young. The reason is very simple - She likes travelling. Taking a job such as tourism guider can allow her to travel all over the world.

Obviously, money is not the only reason for people to work. Sense of responsibility, tendency of self achievement, or maybe just interest can play an important role in people's career
