What is the most important book you have ever read? So far, I have read many books most of which were important to me. But, one of the most important ones was the biography of Albert Einstein. This book was so important to me for many reasons. Before getting started, let me define what a biography is. A biography is a book that tells what has happened in a person's life. Before reading that book, I thought that Einstein was from a prosperous family and was always the best student in at school and university. But, it was after reading the book that I realized that I was wrong. Indeed, not only was he was from a deprived family but he also lost his father very soon. At school, he was an ordinary student and, actually he did not like school at all. Although he was poor, Einstein was very industrious and ambitious. He loved reading mathematics and physics books. From that book, I learned that anybody, regardless of their wealth and intelligence, can become a great and influential person. Most importantly, I learned that hard work is the main contributor to success.
