Parents are the best teachers. This is an old saying. Some people agree with this statement, but some do not agree. Personally, I think the most important lesson is about our life; so the best teachers are our parents.
Parents have prepared everything for their children. Children learn from their parents how to deal with the problems they face. They get good advices from their parents that they could use in their future life. My teacher always advises me to listen to my parents. He even says that I can get good advices from my parents. Eventually, I can benefit from those advices in the future. My teacher has always been listening to his parents' advices. Therefore, he has made a very good career and success in life.
