You can change your habits by understanding what triggers them and replacing bad habits with better ones. While circumstances are outside your control, your reactions and behaviors are not. Habits are formed from a trigger, mindset, and action. By changing your mindset and replacing the action, you can break old habits and form new ones. For example, the author was triggered each morning to feel groggy and drink coffee, but changed his mindset to believe in an alternative and replaced coffee with smoothies, breaking his coffee addiction habit.
