The crux of the problem is overlooking how work can be "positive" too. 9-5 can be pure drudgery that drains every ounce of your energy, but if you can find work that is fulfilling, putting additional hours won't exhaust you; in fact, I think it'll recompense your lost spirit at job. I would go far as to say that, expending your time in watching TV, video games, social media is more wearing than people realise. I have seen myself exhausted on days where I managed to do nothing at work; and highly motivated, when I achieved something significant.
