Habits have 3 stages. A trigger, a routine and a result. Keep the trigger and result but change out the routine for something else, something better, healthier, more fulfilling, more productive. In all instances the trigger is a powerful thing to identify and set into a routine pattern if you want to enforce it. A lot of links to aviation safety and the potential to transfer them into other sectors – Medical, petrochemical, construction, service – the list is endless really.
A great book if you are trying to either replace a bad habit or start a new one. There are regular discussions as to the amount of time it takes to adjust or start a new habit and these range between 30-60 days depending on who/what you choose to believe.
