It is an interval long enough to facilitate profound recognition, immense exuberance, a numbing fear, a life-changing departure or a paradigm-shifting and positive awakening. Don't underestimate the magic of a brief but vital moment.What can happen in the space of a single heartbeat? Everything and nothing. It is but a fleeting event - yet, under some circumstances, it can come to represent all the time in the world. Are people fundamentally wonderful? Are they loving, kind and happy? Or do they secretly harbour grudges and selfish plans to impede one another's progress? Our answers to questions like these depend on the mood that we happen to find ourselves in. When things look good, we feel good. And when we feel good, we see the good in those around us.
