    My friend Henry, with who I studied in the same class, didn't like studying at school. That's because he couldn't go to high school. He had to return back to his hometown, where his father wished him to learn to manage our small shop. However, the young man was not interesting in it and didn't do as his father said. He spends a lot of time reading and he also learned how to repair cars. Last month, I received an e-mail from him inviting me take my vacation on his hometown. I started off. Seeing that he was such successful, I said, “Henry, all road lead to Rome. You are great!”
