We get lulled into patterns of thinking and acting. The is fast, that is slow. Open this door, not that. This person produces results, that person always hesitates before acting. We do this until our pattern is interrupted. If we are adventurous enough we put ourselves in unique environments then weak ideas influence our worldview.
We can interact with a different group of people, attend conferences that attract a different tribe, read from peripheral sources, or just try to get lost and search for a way back. Otherwise it takes the unexpected to jolt us awake. When our paradigm is flipped by the irrelevant becoming remarkable.
