Changing your job.
Some people say that Americans go to work with resumes in their pockets. In this country, it is not unusual for people to change jobs frequently; changing jobs is a way of advancing professionally and financially. It is not considered strange for a person to have three or four job over period of ten years.
If you have a job and want to change it, keep the old job while you look for a new one. Having a job gives you an adventure. You can take your time and be selective. You also have bargaining power. You may get a better salary offer if a prospective employer knows you are not in urgent need of a job.
