I recommend the book "The Life of a Winner in the City". The female protagonist, Zhong Yue, is an ordinary office worker. She has been working hard in the city for many years, but she still can't succeed. However, when he obtained an extraterrestrial technology, the Child Development Support System, he worked hard to earn money, changed his mindset bit by bit, and finally became a winner in life. This book met the requirements of the inquirer. The female protagonist used her intelligence and the business she managed to become a winner in life. I hope you like my recommendation. Muah ~
