My personal opinion on the causes of the inability to keep virtuous habits is that people lack external stimuli, review and pressure. Talk to teenagers who train for swimming competitions. They have to be in the swimming pool by 6:30 or 7:00. This means that they, their instructors, their parents, even the swimming pool janitors will have to wake up at around 5:00 or 5:30, every day for years and years. Unsurprisingly most of the swimming athletes wake up at those ungodly hours and do that for years. I suppose that the thing that helps swimmers wake up early is the social stigma that would arise from being late. Being late means disappointing your instructor and wasting the time of your parents and all the people that work at the swimming pool. This pressure, if well balanced, keeps you in check, even after the Hawthorn effect fades away.
