Whether we are happy or sad, loving or angry, or wise or foolish depends on what’s inside the brain. Bringing good things into your brain is the key to well-being and effectiveness, psychological healing, creativity, and spiritual practice.
So, how do you get good things—such as resilience, self-worth, or love—into your brain? These inner strengths are grown mainly from positive experiences. Unfortunately, to help our ancestors survive, the brain evolved a negativity bias that makes it less adept at learning from positive experiences but efficient at learning from negative ones. In effect, it’s like Velcro for the bad but Teflon for the good.
This built-in negativity bias makes us extra stressed, worried, irritated, and blue. Plus it creates a kind of bottleneck in the brain that makes it hard to gain any lasting value from our experiences, which is disheartening and the central weakness in personal development, mindfulness training, and psychotherapy.
To solve this problem, Hanson developed the four HEAL steps of taking in the good: Have a positive experience; Enrich it; Absorb it; and if you like, Link it to negative thoughts and feelings to soothe and eventually replace them.
