#define overworked
I think people who enjoy their jobs / work will happily do a lot of hours in it, those who don't like their job will likely get stressed, irritated and / or angry if overworked. Take games for example, it is very easy to dedicate enormous amount of hours playing a fun game, even staying up past your bedtime or making time for the game. This is because you are having fun, if you are having that much fun in work, you will likely not care or even complain about the hours.
How many hours a week you spend coding, and
how many hours a week you spend reading about programming?
I have far too much fun programming so much so that I gave up playing games for it and by the looks of it this probably wont change, I usually do approx 98 hours a week (researching and programming), but I don't consider it 'work', I do other stuff too like working out, cooking and ofc playing with the cat. I'll admit I no longer have a social or sex life, cant even remember the last time I was in the sun and unless it is technology / political related (mentioned in parliament) I have no idea what's going on in the world. A little too much info I guess, my point is, if you are having fun the time will fly by and you wont really care to question it and happily sacrifice hobbies / tasks so that you dedicate more to that work.
I think if a person is feeling overworked, they need to find out what it is that is making them feel like that, it isn't always the hours that makes them feel overworked
