But everyone has different prime hours (a great HN comment on why we all have an energy problem, not a time problem: https://news.ycombinator.com/item?id=16074674).
What time of the day are you the most productive? Would love to hear your thoughts on how much you guys "actively" manage your prime times (and control your daily productivity). Working on a http://mailbrew.com feature that highlights managing "the ideal time of the day" people would "consciously" allow distractions but not sure whether enough people are aware of peak time management concept, never mind using it to receive daily digests. So hesitant whether to position such a concept a unique selling feature.
Second best time: late night.
I've tried for years to adjust to a morning schedule, waking up earlier, etc... It was never as productive and I'm always left feeling tired. Adjusting to sleeping earlier and getting up earlier worked for awhile but wasn't as productive as simply working at the above optimal times for me.
If I wake up at 8am, my morning is subpar and I will perform best from mid-afternoon to late evening.
In the afternoon I experience the usual energy slump.
