It is important to calmly handle complex situations, as well as complex and vast amounts information.  Being able to do so demonstrates a certain level of intelligence and mental holding capacity.  We become mentally stronger and gain templates for future complexities.  We see how to store large quantities of information and apply it in the proper situation.  Our brain makes rubber stamps and is malleable to alter its templates for novel situations.

Becoming more aware of the vastness of the world allows each of us to focus on a small part of the vastness while recognizing how that information fits into the larger system.  In addition, the vastness of the world humbles us all, allows us to be compassionate, and forces us to ask deep questions that furthers the breadth of knowledge.
