There’s a chance you’re facing challenges in a hamstrung way, and there’s an easy solution: Get more sleep, says New York Magazine.

Bear with me here. There’s voluminous evidence that those countless little decisions that, when added up, lead us to fail or succeed at our New Year’s resolution — take a cookie or leave it; go to the gym or stay at home watching football — are affected by our level of stress and exhaustion at a given moment. “When you’re tired you lack the self-control to eat healthy and the focus to be productive,” said Dr. David Wagner, a sleep expert at the University of Oregon’s Lundquist College of Business (full disclosure: we are colleagues who work across the hall from one another). “If you want to reach those New Year’s resolutions you need to gather the power to pursue them. That power can come through sleep that is better, longer, and more regular.”
