One of the most important things you can do for yourself is to recognize the distinction between your "job" and your "career". A job puts bread on the table. It's just a job. A career is what you were meant to do, what you love to do, whether it makes money or not. A job focuses on your immediate needs, like money to pay the mortgage. A career focuses on your wellbeing. And by extention, the wellbeing of others surrounding you.
Most peoples jobs, are not their careers. When you get out of college you think ok, I'm going to get this job in this industry and make a career out of it. Most people get stuck there. They live their whole life climbing a ladder they know in their gut doesn't really make them happy. Others recognize the disconnect. They hate their job. They think, is this it? Is this all there is? What they really hate is the fact that job is keeping them from what they really want to do. They would love to be doing something else. Well, that something else, or perhaps something something else, is their real career.
