Researchers believe these daily habits will train your brain to achieve better overall well-being. (Worth a try, right?) A research paper recently published in the Proceedings of the National Academy of Sciences offers a mental training plan that its authors call the “how” of well-being. Their findings suggest there are four key behaviors that tend to contribute most to overall satisfaction. And they see their plan as a way in which people who already feel relatively healthy can cultivate mental wellness on a daily basis.
