Most people are looking for the perfect job. They want a job that is interesting, with a good salary and not much stress. However, it is difficult to get everything. Healthy, relaxing jobs are usually not very well paid. On the other hand, people with stressful job often get to good salaries. For example, the head of a big company gets a lot of money, but he or she does not always have good health, or the time to enjoy life.
