Nature verses nurture is a debate that has raged on for years, and occupied the minds of scholars and psychiatrists alike. Are our personalities and characteristics formed in reaction to our environment or from an innate sense of self? Either way, parents across the globe are constantly voicing their 'secrets' of raising a smart and inquisitive child - and though the methods may differ there is one key aspects that they have in common. Reading.
From celebrities to business leaders, the majority of them agree that reading to a child from a young age helps their cognitive and emotional development.
But which books are best? We have collected a selection of five books that super successful people claim to read to their children, along with their reasons as to why. How many have you read?
1. Homer's "Odyssey"
One of the most famous books in the world, the story of Greek hero Odysseus, from his departure from Troy to his long and arduous journey home to his wife Penelope. The book is hefty, and can be difficult to understand - but the heroic story of a long-lost King will have any child gripped.
Anne-Marie Slaughter, President and CEO of think tank New America, told NPR as part of the Storybook Project:
"Reading aloud was my favorite part of being a parent to young children, hands down. I often hunted up and read them books that my grandmother read to me and that I can still recite together with my father. They are enchanted stories, shared memories, distilled love.
"One day when they must have been about 5 and 7 I brought home the actual Odyssey, in Fagles' wonderful translation, and just read them the first page or two so that they could hear what the real thing sounded like.
"They loved it; we read it slowly, but all the way through."
