It's important to take this as a self-help book and not literature or novel because it's really not very well written. It is super literal and leaves nothing to the imagination. That writing mantra, show don't tell? Well this is all telling, no showing. We don't witness a journey and uncover a message for ourselves, we are verbatim spelled it out from page 1. It could be that this book hasn't dated well as these ideas are not new anymore... Think The Secret, Eckardt Tolle, Alan Watts etc. Of course the underlying message is good and helpful reminders of what we know to be true, but if you're into good writing you may be frustrated by the unimaginative storytelling devices and surface-value characters. It's also laiden with cliche and today feels very 'nineties'. It's an easy read but can be quite painful!
I also realised after time the irony in the title. He *sells* his Ferrari (he doesn't give it away or let go of his worldly possessions, he exchanges it for cash... which fund his travels.) So still playing into Capitalism and what I would call the cult of enlightment or the commoditization thereof.
