But a wise turtle asks him four questions, and everything changes. He realises that all his problems are not caused by things, but by his thoughts about things; and that when he questions his thoughts, life becomes wonderful again.

This is a heartwarming story with a powerful message that can transform the lives of even very young children. Byron Katie's wisdom-filled words and Hans Wilhelm's vivid, magical illustrations combine to make a book that will become one of the classics of children's literature.
