Imagine a 1-hour task taking 1-week to complete.
It sounds crazy, but it happens all the time. Research from 2016 claims that people are interrupted 50-60 times during an average workday (about once every 7-8 minutes). Worse, distractions tend to lead to more distractions. That "do you have a minute" coworker question becomes a 20-minute discussion about 2-3 other things. And, oh, by the way, one of them is urgent and needs to be done right now. The distraction rabbit hole runs deep.
