Differentiate from the two.
There are times in the day when I am doing three things at once, cruising through my to-do list. Things for the most part that do not require too much brain power, so I can afford to spread myself thinly across many.
Important work however which requires focus is when I purposefully close myself off from other distractions, allowing me to go deeper which in turn increases the quality of the output.
If you mix the two you might feel busy but is it of any significance?
