I'm one of these people. Used to be an absolute workaholic, now I work as slow as is humanly possible. It works for software development since it has this weird property of not really improving much if you speed up. Someone can be really fast and not get much more done than someone who purposefully takes their time.

My brain tells me when to quit each day and it has helped tremendously with preventing burnout. I might code for two-four hours per day. However, I don't try to avoid work or block projects or steal credit and I'm always game for a new project--though I hate building greenfield apps because it seems like the devs are the only ones into it and I thrive on being part of a cross functional team.

I'm on a project right now where we developers are driving out every requirement. The business is very behind, hasn't really driven any requirements. I warned everyone at the beginning that we were going to outrun them. A few devs were pumping out code like crazy and I tried to just chill. Now we're scrambling for work--well, I'm not.
