A job is temporary. A job is fleeting. You are not in control of it, it is in control of you. Most jobs do not require specific skills, or if they do, often you can learn what you need to know on the job. You show up for a job everyday, but the job goes on without you if you leave. For the most part, you do not control the direction your job takes, the choices you make my subtly affect the way the job goes, but you are not steering the boat. With a job you are usually working for someone else. Being paid by someone else. Dependent upon someone else.
