"People suck at following advice. Even the most effective people in the world are terrible at it. There are two reasons: 1. Most people have an insufficient reason for action. The pain isn't painful enough. It's a nice-to-have, not a must-have. There has been no "Harajuku Moment." 2. There are no reminders. No consistent tracking = no awareness = no behavioral change. Consistent tracking, even if you have no knowledge of fat-loss or exercise, will often beat advice from world-class trainers."
