Robot Green was 31years old when he went to college. That was his first time he came into the classroom. Eleven years later he received a doctor’s degree in physics. Robert Green was a good example in studies for all people. His life was a moving story.
From a young age, Robert Green lived a simple and poor life with his grandfather in the mountains of Boston. His grandfather taught him to read. Later he taught himself to read Maths books and Physics books. From time to time, he bought old books with his saved money and read them all. At that time few people in Robert’s neighbourhood knew about his love of reading and learning. But one person, Jane Keller did know him. She worked in a library. Robert used to go there and he read everything in it. She suggested books for him to read.
A year later, he entered Bethel College. He was interested in everything that he had never seen before. He got an A in every subject. To his teachers’ surprise, he finished college in three years. His teachers encouraged him greatly and he went on his education at Stanford University.
