For me, it tends to be "all or nothing". I may be totally obsessed by my project, from the moment I wake up until I go to bed. I want to see it working, or complete a last feature, or a cool refactoring. I agree it's draining and not healthy but I feel I don't get much done if I only work a few hours. Besides, sometimes it takes time to warm up, and I don't want to break the flow. Alternatively, I can be disinterested and I will be slacking for some period of times, could be weeks. I would add some doc here and there, fix a few bugs, discuss with colleagues, learn about new techs. But then, I feel guilty and anxious and overall not happy. I wish I was able to be motivated everyday, work 7 hours of productive work and call it a day. I haven't found a working mode where I feel productive and motivated for long period of times.
