The main meaning of the first two sentences is: since you have chosen your own goals and ideals, you will definitely stick to it unswervingly;
The main meaning of the last two sentences is: It means: If a human doctor wants to achieve his long-cherished wishes and wishes, he must persist and work hard.
This is what Li Shizhen, a medical scientist and pharmacologist in the Ming Dynasty, said when he was young and asked his father for advice and made his determination to practice medicine. It also has great enlightenment significance for us in the modern era.
