Rick Hansen is a psychologist who studies how we can change our brains and our minds for the better. He says taking in the good has four fundamental steps that I remember with the acronym HEAL, H-E-A-L - which stands for have and rich, absorb and link. We're going to tilt that bias in your own direction, making your brain more like Velcro for the good and Teflon for the bad. If the mind could be likened to a garden,. we can witness the garden, we can pull the weeds, and we can plant flowers.
