I’ve been lucky enough to have a manager that doesn’t care at all about about how much time I’m working, as long as I’m consistently delivering what’s expected of me. This has allowed me to optimize my day and at the end I end up working about 3 focus hours and that’s it. Analyzing my days I realized that I’d spent way too much at “at work” but “not working” (i.e. time in HN…) so I ended up cutting all of that time, and if I’m ever not focused I don’t even try to be and switch to some other activity. The end result is that, 2-3 hours of focus programming time a day, ~5 hours of meetings on a regular week and that is that. The bane of this is managers that want a response from you at any time of the day within 5 minutes… but if you have somebody that is understanding and you are able to reach an agreement to compartmentalize your time (i.e. I won’t answer to messages until after lunch because it’s my focus/productive time) then good agreements could be reached!
