I wanted to become a teacher since first grade. In sixth grade, I started to learn geometry and was entranced by the logic of geometric proofs-the harder, the better. I loved to explain the problems to other kids. Since then I knew that I would be a math teacher. My father once asked me if I couldn't be a math teacher, what I would do. He thought I would be a good programmer or a math scientist, but I answered that even though I liked math a lot, and I was good at it , I could live without it, but I couldn't live without children, so I would find some job to be with kids.
