Let us think. Here, say, offer me a salary several times more on the condition that I will work the same time more intensely, it means more tired, it means more time to spend on recovery... That is, in my personal free time I will not engage in some of my pleasant things (read, draw, communicate with friends, spend time with family, etc.). and etc.It is stupid to get rid of stress at work. Why do I need money in such a way? Buying antidepressants? No thank you.
The most desirable thing I would spend any money on is my free time. And, in fact, working behind the sleeves for a small salary, I buy it.
