one sentence takeaway:
"people can plan to concentrate on important tasks when their mental resources are at their peak for avoiding distraction. Our research found that most people have peak periods of focus in the late morning and midafternoon."
I must be one of those outliers then because I tend to have peak periods of focus around mid afternoon and night time.
It makes working a 9 to 5 really difficult because I feel like I do not "wake up" until more than half the day is over.
