It's important to understand that the human brain is filled with meaningless chatter. Improperly trained or augmented, it jumps between reliving past humiliations and worrying over future hypotheticals. This can cause serious inadequacies when the need for decisive action arises in the present. There are, however, small evolutionary benefits to this chronological chaos. Those with no concern for the future often fail to prepare for it adequately...while those who cannot remember the past are...condemned to repeat it.
