Job vs. Career
There are many differences between having a job and having a career. My opinion is that a job is something you do to make money, whereas a career is long-term and something you invest your time and energy into. You build towards your career and try to keep leveling up towards an end goal. A career, since it is long-term, is hopefully something you enjoy doing that will keep you engaged and satisfied.
Something to keep in mind is that even if you love your job or career, it shouldn't define you. It should motivate you in all areas of your life. For example, you can love your job or career and still maintain other interests such as traveling, helping others, etc. Keeping up with your outside interests will help you see things in different ways, which could help translate into better insight with your job.
