People have different styles of working. I have found that if I am deep into a problem, dedicating long hours to solve it is more productive as I have the context for longer time and can try out different things as I am deep in the zone. It is not as simplistic as "they work long hours because they don't have product market fit.". I like to solve problems, engage my brain, and the kind of intellectual simulation I get while working is something I can't get outside of work. I would regularly dedicated 12 hours a day and work on weekends, and when I am out of the zone, I will take a break for a few days, recover my energy and then go back to work. I had an employer who was exactly like that, so understood it better than others, giving me the leeway. Infact, most of my colleagues were like that. We had our own social life beyond the office, but I did not feel like socializing everyday anyway.
