I'm married to a scavenger of sorts and he often totes home rescued boxes of books that I paw through with shiny, hungry eyes. I pull out the odd and interesting and add them to my teetering stack.
Other than some interesting math and some good, general advice, I really don't put much into the theory that our birthdays determine who we are "meant to be." The section on "Laws" was interesting to read - I especially resonated with the "Law of Cycles." I'm all about the circle, y'all. Other than that? Kind of a waste of my precious reading time.
