What does it all mean?

Quote

Are the ideas I am compelled to write simply messages I have in another time and place left for myself to help me remember my soul’s mission? 
Checkpoints internally engraved to guide my journey to where I am meant to arrive? Do I somehow already know the path ahead and in a greater realm of reality I was given the gift of enlightenment to use in the lives I will live over the course of my perceived eternity? 
Do we live life unaware of the game, unaware of the objective and blinded of the truth in it all… Are each of our lives a needed existence in order to advance humanity? Are we individual vessels called upon as a collective to illuminate the essence of one?
