The better you get at things, the more curiosity, passion, motivation, creativity and ideas follow.
Some things might be more attractive on the surface than others? They might be more _fascinating_ so there is an initial drive to explore.
So I don’t know if there are general rules like this. For me it’s tied to making things, mostly mistakes, and getting confidence through learning. This has an exponential effect on the rest.
Everyone has something that they can do better than anyone else, and give something to the world that no one else can, and that's the best direction to put most of one's effort into.
In a healthy society, it might be prudent to factor money into it as well, I've found it leading me down all kinds of wrong and fucked up roads, where I was making "good money" and was "good at my job" but felt miserable as fuck all the time.
His solution to this was to pick any trade or skill and to explore it via mastery. Deliberate practice and, as with this piece, curiosity to "find" the bits of it that you are good at and enjoy, then focus on those aspects to get enough skill that people will pay you money for that skill. That isn't "passion" in the sense that most will think of when "following your dream" but you end up with a core trade and skillset that you are good at, you enjoy and differentiates you from everyone else in the market (or puts you in a small enough resource pool that you're always in demand).
I feel like this article touches on that to some extent, but opens up similar blind spots to a "passion" oriented mindset. Instead of "what if I'm not passionate about anything?" you have "what if I'm not curious about anything?". Both require an unwritten first step of discovering your passion or curiosity. Both don't have a coherent roadmap or end goals, so while one person may find following curiosity to be a better path (as they're able to untangle a thread or find a new one when a line of curiosity has been satisfied) another may find better success by using their "passion" as a guiding star.
Fun to think about anyway, but it's definitely true that both philosophies hide or downplay the amount of work required to turn your passion or your curiosity into a paying job.
