Don't let the covers fool you. Books, like lives, are wiggling, evolving, living things. They're not bound by pages or authors or schools of thought. They're not born when they're printed; in fact, they only start to live once they're read. So first of all, we thank you, reader. You dignify this work we do, and we're sincerely grateful for your time and attention.

Learning to sit with ambiguity can be a very important start at a life liberated from anxiety—and the way to do it is to resist the urge to chase answers to questions that may actually be unanswerable.
