Tip: Start the day by writing down the One Most Important Thing you need to get done today. Then focus & get that thing done, *before* opening email/slack or other distractions. Then, whatever else happens, you've already had a pretty productive day and can feel good about it :)
@TuX_Illindi Yeah, if it's too big you'll need to split off a suitable chunk from it. On the other hand I've been surprised at how fast even a somewhat large task can get done when given sufficient focus.
@LatJosef And that of course begs the question: Are you sure you need to answer all the emails? Or are you just letting other ppl impose their priorities on you? Speaking from personal experience :)
