There is an emotional pattern to our daily lives. There is a genuine mood of positivity that peaks during the morning, drops during the afternoon, and then climbs back up in the evening. This prevailing cycle of moods happen every weekday to everyone, regardless of race or nationality. Behavioural scientists from Cornell University using the Day Reconstruction Method (DRM) and going hour by hour through people’s lives found the same pattern.
