“For so many reasons, quitting is hard, and we can’t tell you what the right decision is. But knowing the factors that shape our reluctance to give up, we can say this: If you’re feeling not just frustrated and challenged, but helpless, isolated, and trapped, like you want to hide in a cave, or like you’d rather put your hand in a toilet full of tadpoles than spend one more day doing the thing, you should definitely quit whatever it is.”
