A pretty good article, but I will differ a little.
Foremost, one's passion may not be worthy of making money.
I have no doubt I would probably qualify for a professorship in ancient history and occultism, and I could likely pass a challenge to any seminary wrt Biblical matters...
But my passions, I learned early on, were not something I could make money doing. They remain my focus, but my side hustle has always been my money-maker.
Guitar is another example. Before my illness, I could three-finger pick, chicken pick, could run a guitar, electric guitar, bass, and banjo... And I was good as a front man in a band. But for all of that, by my mid 20s I had to come to grips wit the idea that I was never gong to be any better than a crappy band member playing covers in crappy bars. Being a Country music star was just not going to happen.
More to the point, one must learn to find passion in what you do DO for money.
I loved the craft of timber framing, and timber and rock retaining walls... I poured my soul into it because of its craft. I loved the precision and beauty of machining and computer sciences... The elegance of computer languages, the thrill of hacking viruses. I loved the camaraderie working on construction crews, and the magic that happens building a house with crews and contractors that have learned how to dance... I loved the efficiencies of a production shop floor, the challenges of landing on your marks juggling project schedules, heck, even putting out the endless fires that are the process of management.
Following your passion is overrated. Finding passion in anything you do.... that's where it's at.
An old indian taught me to sit still anywhere I am, and be quiet until I could see the beauty of the place. Easy to do in the majesty of these mountains I live in... but do the same inside of a ramshackle house, long abandoned... Or inside of a box car, or in a parking lot.
It will surprise you where you will find beauty.
Passion is much the same thing. You should be able to find passion for anything you do.
