According to McGonigal, the practice of meditation is an effective way to establish the primacy of the prefrontal cortex, thus enabling a choice to do the harder thing, when that is required for attaining a long-term goal. McGonigal believes exercising self-control can help build up willpower in the same way as, over time, physical exercising can increase capacity to exercise. She says: "If you do it with awareness and intention, it can make you stronger. The strength develops over time, even if you feel temporarily weaker. But I think this only works when you have this mindset, and feel like you are consciously choosing to "use" your willpower. If you feel like you are being drained by everything you "have" to do (or not do), that lack of autonomy is even more stressful than exercising self-control."Kelly McGonigal's comment on The Willpower Instinct The promise of happiness from cravings often misleads in McGonigal's view, and she gives techniques of mindfully focusing attention on the actual experience when indulging a craving or temptation, so as to compare it with the expectation of reward that preceded it.
