People predictably underestimate how much they work, especially when they’re working long weeks
Working more than 40 hours a week is useless anyway
Interruptions take 15-20 minutes or more to recover from
People spend a stupid amount of time doing non-work things at work
People are absolutely terrible at estimating how long it will take them to complete any sort of task imaginable, and not in a good way like “surprise wow that took less time than we thought”, but in an “oh fuck that took way longer than we thought” way.
