If you grew up in an unusual family and felt limited by heavy thoughts, how would you change your life story? In the book Educated, the writer Tara Westover shows us how she dealt with hard times.
The book talks about Westover's life. Her father had a junkyard (废品场) in Idaho, US. It's a very small mountain village. Westover and her brothers and sisters worked every day. Before she turned 17, she had never travelled outside. None of the kids in her family had ever been to a school or a hospital. As she got older, she felt that she needed to get away from this uncomfortable situation. Luckily, Westover's older brother taught her to read. With hard work, Westover went to college on a scholarship, and later got a PhD (博士学位) in History at Cambridge University.
Education changed her, her life, her way of thinking and even her luck. After reading the book, I come to feel the deepest thanks for my own family, and the education I got. Education allows girls like Westover to fly like birds towards their own goals. It allows us to get a different view, find new experiences, better understand others and explore the wider world. I wish for all of us to be like free and powerful birds, growing and changing through challenges and difficulties.
