What has happened in the past has happened, written into the pages of history, it cannot be erased; the future is uncertain, unwritten; regardless of what plans you may have, the future is ultimately beyond your control. Your entire life, and for that matter the entirety of existence in and of itself, has served to fulfill one single purpose, to bring you to the very moment you are in; this is the only moment that exists; this is the only moment we have any control over.
