But here’s the problem: your brain preferentially scans for, registers, stores, recalls, and reacts to unpleasant experiences; as we’ve said, it’s like Velcro for negative experiences and Teflon for positive ones. Consequently, even when positive experiences outnumber negative ones, the pile of negative implicit memories naturally grows faster. Then the background feeling of what it feels like to be you can become undeservedly glum and pessimistic.
