if i had to do this for work, in a way you could argue all above is good if work does not feel like work. but on the other hand, the addictive and all consuming nature of it has some kind of a drug like quality, where i question if the activity of coding/programming itself has some serious unhealthy side effects where it can take over your whole life (in a sense) and hence you become some sort of a zombie like character staring at syntax all day. sure your employer will be delighted (if you do this professionally) but is it healthy for the individual. its a complicated question. maybe one could phrase it in a different way or express it better then i can.
