Willpower, a finite resource, is what we turn to when we want to make something happen or stop. We can endlessly criticize ourselves for not being able to resist food or for getting angry, although we know it’s not good for us. Yet willpower uses often more energy than managing the environment and the situation. So instead of getting angry for eating something when we are super hungry and vulnerable we can instead use far less energy, if we don’t let ourselves get that hungry in the first place. Whatever behaviour we are trying to start or stop, the environment plays an important part and it’s often easier to change than you might think.
