But have you realized? In the process, you’ve unknowingly convinced yourself that you’re not happy, and are bound by a standard of happiness set by someone else. In fact, 99% of happiness is already within your reach. Yet, for some reason, we tend to focus only on the “misfortune” of the remaining 1%. ■ Unraveling preconceptions one by one

Galactic butler Torataro, well-known for his YouTube show “Quote Therapy,” will be DJing to show you how to release the “preconceptions” that get in the way of happiness. This book will be a special one that will gently nestle in your heart, like a star shining quietly in the night sky.
