Another big reason our resolutions fail is that “we lack a sufficient structure for support,” Miedaner says. “If you are changing a bad habit or starting a new habit, it could take months before the new habit is in place. During those first few critical months, it makes a massive difference to have a really solid support system in place. For example, if you want to go gluten and dairy free but are left wondering what to eat or cook, you could hire a chef for 2 months to get you started. You'll learn how to cook in a new way without your standard ingredients.” If you can’t afford to hire a chef, a trainer or a life coach, talk to your friends or someone you want to make proud. That adds a sense of accountability, which many experts say is vital to success.
