Negativity is natural because our brain zooms in on problems. We feel good when we solve them, but our brain immediately shifts to the next problem. You miss out on positivity when you see the world through this lens. Fortunately, you can build a corrective lens that lets in the good that your negative lens has screened out. You can reduce the stress / anxiety of cortisol and stimulate your dopamine, serotonin and oxytocin in new ways.
