There are only two purposes for working: to sustain oneself and to learn something. It’s not about changing your fate or accumulating wealth. If neither is achieved, then you need to switch. However, when it comes to learning, everyone’s comprehension is different. Some people can still learn in harsh environments (the ability to learn secretly: high self-reflection ability, sensitivity to systems, the ability to transform pain into information), while others suffer immensely (understanding pain, passively accepting knowledge).
