Thank you everyone for your responses! I was thinking about rationalizing this , and also about effect of my work that matters rather than hours sited at my desk, and also that human beings are not machines. My goal was to park all non-work time and spend it with family, playing chess to get into the flow feels like non-work time... Maybe what I wrote feels like exaggerating but it comes from my other thoughts I had about life. Mainly that if I ever want to start something on my own and in the same time not to make my wife to divorce me is to become more efficient with time I spend at work. When I feel I waste time this makes me frustrated and some of that frustration leaks to my home-time... in a way that sometimes I have a feeling that time not invested is time wasted. I feel like this especially on bad days where I don't feel like I have done enough. I know the answer is simply "don't waste time", it feels awkward but it's like addiction and I don't have good idea how to fight it.
