Nice list about our emotions.
8. The Law of Conservation of Emotional Momentum
Time doesn’t heal all wounds – or if it does, it only does so indirectly. Events can retain their emotional power over the years unless we re-experience and re-evaluate them. It’s this re-experiencing and consequent re-definition that reduces the emotional charge of an event. This is why events that haven’t been re-evaluated – say, failing an exam or being rejected by a potential lover – retain their emotional power across the decades.
