WHY PEOPLE WORK

All of us know that we have to work hard to earn a living ourselves and to support our family. However, we work not only for material life but also for many things that are beyond gaining money. We are working to affirm our ability on a certain field. We feel self-reliant, self-confident, and proud because we are financially independent.

Anyone who works is regarded as a useful member of society. We are working that means we are contributing useful goods and services to our country.

Working helps us train our skills and talents. We always try our best to do a good job. The better we work, the more money we earn and that motivate us to work harder. Without working, a man’s life will be empty, purposeless and meaningless and it is easy for a lazy jobless man to do wrongs.
