When I was young, I travelled across the country and took a job without really asking what my responsibilities were or how much I would be paid. And I worked 14 hours a day with a half day off every other week. And I learned so many things that permanently improved my life.
BUT, I had to quit after nine months because I was working so hard I had burned off all my body fat and was starting to burn muscle. I was peeing protein. I broke down. I also was not making
enough to cover the very, very basic costs of living: food, extremely basic clothing, and the ability to go to a doctor. Sometimes my employer couldn't pay my salary, so I would be left figuring out how to pay for the groceries to fuel 14 hours a day of labor.
I see both sides and find the original post deeply insightful. But, at the end of the day, while I could go an work epically hard and change my life forever, I could not STAY.
