Personally, my goal is to buy an expensive item (property/house). house <- resource accumulation <- in-demand skills <- study I learn what is in-demand. And then I acquire those in-demand skills. Then I practice those skills to earn the money I need to attain my goal. But that's just me-- my goal is to earn money quickly. This is why I focus on in-demand, popular, low-barrier languages & frameworks: python, javascript, SQL related ones.
