According to Nobel Prize-winning scientist Daniel Kahneman, we experience approximately 20,000 individual moments in a waking day. Each "moment" lasts a few seconds. If you consider any strong memory -- positive or negative -- you'll notice that the imagery in your mind is actually defined by your recollection of a precise point in time. And rarely does a neutral encounter stay in your mind -- the memorable moments are almost always positive or negative. In some cases, a single encounter can change your life forever.
