There are many reasons why people have different perspectives on work.
A lot of it has to do with where you are economically. The need to feel economically safe sometimes must be met before you can start to think about “what you want to do with your life”.
When I was in undergrad, I was not thinking about what I would like doing day to day. I was focused on “working for a good company” and getting benefits. Only after I was working for a few years and had some money saved up did I even allow myself to think about my options and future.
But I don’t think money is the only issue.
Another reason is that our natural talents may not have been accepted by our families. Many people are encouraged to play it safe: go into law or medicine, work for a Fortune 500 company, etc. To take a job with security and to aim for jobs with prestige. If you are naturally drawn to politics (for example), but your parents despise politics, chances are you may have some conflicting feelings about pursuing a career in politics.
If you love art, but your dad thinks art is a nice hobby but not a job, you may have a hard time getting in touch with this side of yourself.
Finally, I believe that some people are on different stages of the same path. For example, my father was a laborer and he only finished the 4th grade (he is an immigrant from Sicily). For him, work was a way to provide for his family. He had a love of history, but because of his circumstances he could not become a teacher or professor (which is what he really wanted to do). However, he emphasized education, as did my mom, and both my brother and I went to college. My father sacrificed and worked so that I could fulfill my potential.
