I don't understand where this idea came from that you must do the kind of work that you love the most to be satisfied with your job.
This is almost a delusional idea. For hundreds of years, people have done things they had to in order to survive. Even now, we have people doing all kinds of jobs, some of which are just dirty, disgusting, exhausting, and just terrible. There are jobs that involve dealing with trash and shit. Jobs where the work is essentially abusing their own body, manipulating people, doing all kinds of bad things to the environment, etc. I don't think a lot of people had these jobs on top of their lists of what they love the most. They took them because they were things they could do, and more importantly, jobs they were able to secure.
Or they do them in order to earn enough money to do things they really love. Like this photographer who told me he came to hate photography when it became his business and he had to do stressful wedding photography seven days a week, deal with the messy business side of things and all the paperwork, just to make ends meet, than to follow his passion of creative nature photography.
So he went into advertisement business instead, got a soul-sucking job where he makes 150k (well over twice his wedding photography business), but with that money now he is back to actually enjoying photography once again. He can afford to buy expensive equipment and do photography only for his own happiness.
So, what I am saying is that making money is a GOOD criterion to use to narrow down what you want to do. It doesn't mean you're shallow or greedy. Frankly, if you've ever known, in your bones, the hell that is being dirt poor, doing anything not to live that life again is as good of a motivator as any.
And here's one last thing: Even if you do what you love, and the work is in very high demand and pays so much money, it is very unlikely that your job or career is going to involve only the aspect of the thing you find so exciting and enjoyable. A job is a job, not a hobby. It is one thing to enjoy programming during weekends and dream of making your own video game; it is another to have to figure out the messiest code you've ever seen in less than two weeks and having nonstop meetings where you have to try to explain clients who know nothing about coding why you're not finished yet.
I could go on, but my message is this:
It's okay to look for jobs you're not in love with. It's okay to ask how much people in a certain career make and let that inform your decisions. It's okay to dislike quite a few things about your job. The idea that if you do what you love you don't have to work a day in your life is nonsense. How many jobs are like that (except in stories)? And if someone tells you otherwise, then perhaps it has more to do with who they are, than the job. In other words, they are likely a very loving person who often sees the positive even in the worst of situations. So they claiming to love everything about their job may say more about their personality and attitude than the actual work they do.
Work can be hard, unenjoyable, and a pain. That's why it's called work, not play or hobby. This is the reality…at least that's how I see it. So, feel free to disagree….
