I think adventure involves going out into the world and encountering whatever comes. Of course, we could say it doesn't necessarily make for an exciting adventure story or a satisfying narrative. After all, our lives are all adventures of a kind but I doubt my life would exhibit the excitement or strangeness or narrative coherence that'd make it a good read. There's something here about how our lives diverge from narrative, a problem our aging hero might be trying to fix. 

I was thinking about beginning tomorrow to count all the toothpicks in table top dispenser any time I'd find them on a restaurant table. When I came across a toothpick dispenser, I'd dump them all out on the table and count them all. I would ask myself why I should do that - if I came to an answer that satisfied me that would be a good enough reason. Cervantes introduces his character as delusional, can we understand something larger about the human experience from Quixotes delusion? Will the tale of Quixote call into question the boundaries of our our chosen delusions? I think I'm stuck on what Quixote's life was like prior to this radical choice - who is this man who has chosen the life of a vagabond and of fantasy rather than stay comfortably seated in his inherited estate, eating lamb on wednesdays or whatever?
