They're not walking too fast but too slow?
Really? I think not. When you are on a fast lane, everyone around you will seem too slow for your pace. Try getting out earlier to head to work one day & see the difference. Try it on a weekday when you're not working. A variety of ways & you will see the difference. The world around you is your very own perspective. You see what you want to see.. Try it with different moods & energy.
A more apparent sample is with Mondays. One of the most dreaded days to many. Mainly due to the 2 days of rest, most people would drag themselves out of bed. Exception are the ones who are truly springs with excitement with the thought of work.
