“It is the neuroscientific evidence particularly which shows us that the circuits in the brain that are important to underlying well-being exhibit plasticity—it changes as a consequence of experience and as a consequence of training. We know that the brain is constantly being changed, wittingly or unwittingly.” The brain keeps changing over its entire lifespan. The good news? We have some control over those changes. “We can all take responsibility for our own brains and we can shape our own brains in ways that are more positive and can lead to the cultivation of well-being.”
