“As part of an effort to prod college seniors to get tetanus shots, a group of students was given a lecture meant to educate them about the dangers of tetanus and the importance of getting inoculated against it. A large majority of those students reported that they were convinced and planned to get their shots, but in the end only 3 percent got them. Bu another group of students, who were presented with the same lecture, had a 28 percent inoculation rate. The difference? The second group was given a map of the campus and asked to plan their route to the health center and pick a date and time to go. Sometimes, you see, motivation isn't our problem. Rather, we need to identify life's everyday mental obstacles - regret, fatigue, overconfidence, fear, to name just four - and put ourselves into position to hurdle them.”
