The author is not considering loving meta-skills. I don't love programming, I do love intellectual challenge. I also love learning things as fast as possible.
If I'd be a cleaner as a job, I'd teach myself how to be mindful while doing it. I'd teach myself how to be okay with the boring/mundane and utilize the job as a tech detox. If I'd be a bus driver, I'd utilize the job as a way to make my social skills better (I've seen bus drivers do that in NL) or I'd utilize the job as a way to reflect on life as I wouldn't need all the brain space for driving the bus. If I'd be a blue collar worker, I'd flip homes since my network would allow for it. I'd also do a lot of crafting on my own.
When one loves a meta-skill, many things become their passion.
