To most people on planet earth, having a job is what marks the beginning of adulthood. Job satisfaction and fulfillment is not at the highest with millennials today. That could be because they are not easily pleased with either their earnings, or how much work they put in to earn that much (or that little) in comparison to how much debt they incurred to earn the credentials to qualify them for the job.
Thus, thousands of people have a job and stay at it so long that it begins to define them. That’s not necessarily a good place to be in. It is important to be passionate about one title or one position, but it is more important to be enthusiastic about one’s work. Your work is your life’s calling. Your work is that one thing you can do with an overarching purpose and meaning for your life. Your job is your training for your work. Sometime your job intersect with your work, and other times your work is your job.
Regardless of whether you are engaged in your work or have a job, give it 110%, but never let it define you. You are more than your job. You could have a dozen or more jobs in your lifetime, and your life’s work does not depend on your defining yourself based on your jobs.
