Here’s a review of the book (often translated as “Please, Be Happy” ), assuming it refers to the popular self-help/motivational work by Alex Rovira (or similar editions under that or a very close title, as the exact phrasing varies). If you meant a different author, this review still captures the essence of similar positivity-focused books. Review: Por Favor, Sea Feliz – A Gentle Reminder or Just Pleasant Fluff? Rating: ★★★☆☆ (3.5/5)
