Habits of extremely punctual people
They're fine with downtime.
Because punctual people give themselves buffer time, they often arrive early—and they are more than comfortable enjoying a few minutes waiting.
Whether they are checking emails, reviewing notes, reading a book, or clearing their heads, punctual people not only enjoy their downtime, but also come prepared with something to do.
People who are chronically late, however, do not enjoy their downtime and prefer the thrill of rushing to and from a place.
If you want to be more comfortable waiting for someone, then bring a book or an iPad to help pass the time.
