So I'm 20 and I've started looking at the salaries of jobs/careers, and this is the impression I've gotten. Like that you could spend years cramming a ton of knowledge about a very niche field, and still only get 2-3x what a run-of-the-mill job makes. Is this true? If yes then I guess this route to wealth would only make sense (due to the diminishing returns) if the topic truly spoke to you, right? Are there alternative career paths to good pay than being really good at something really specific?
After many careers and much money earned and spent, I now try to go by „ikigai“. Its a japanese theory and teaches you to be aware of what it is that you want, what makes you money, what the world needs and what you‘re good at, basically. This is how I went from a very well paid but soul sucking job to a lesser paid but much more fulfilling work.
For me it was building computers and the stuff around it. Its fun and it makes decent money if done right.
Good luck!
