He had seen a career counselor but nothing turned him on enough to seriously look for a job.
At Christmas dinner, one of his relatives who worked for a tractor manufacturer said that the company was in hiring mode. His family pressured him to seek out a job there and reluctantly he did.
He got a job installing dashboards in the tractors. He was not exactly thrilled, but it gave him money to take his girlfriend out.
But he was smarter than the average assembly-line worker and when he couldn't get a question answered by a co-worker, he'd go home and google it. So, pretty soon, he became kind of a go-to guy on the factory floor--he'd come to knew a lot about stuff like mitering and glue.
Soon he got promoted and learned more and more about tractor manufacture, and before he knew it, this liberal-arts type felt passionate about, of all things, tractor manufacture.
Fact is, career passion rarely comes from being in a "cool" career. Because so many people would kill for a career in such fields as entertainment, fashion, and nonprofit work, the pay generally stinks and the boss doesn't treat you especially well because he knows he can easily find a replacement for you.
In contrast, in a field such as tractor manufacture, employers are more likely to treat their good employees well because there usually isn't a line of quality people ready to take the job.
Career passion most often comes from being an expert in a field in which few others are expert, and having boss and coworkers appreciate you and provide the attendant job security and a reliable, decent paycheck. And you're more likely to get those in a non-cool career. Ironically, status and coolness are enemies of contentment.
