I like taking out the trash because it makes my place less smelly. Like, there's a logic to doing some of those things beyond just "somebody told me." But in other situations you find yourself doing things maybe you don't have to do.
The article is pretty much contentless fluff, and would be made 100x better if it was just replaced with the quote "do what you love and the money will follow." Still debatable, but at least it has brevity going for it.
But it's not about money. It's specifically not about money. It's about being happy with your life. And it's less about doing what you love than it is about not doing what you hate. There's an important distinction.
Even if they still have a job.
I remember someone on Reddit/IAmA who hated working for others so much that they figured out how to live on 2,000 dollars a year, and worked 1-2 months a year as a laborer. It happens.
