Based on my own understanding from the above paragraph. I believe Jim is trying to teach Huck Finn how a strong and wise person needs to live. For example Jim says that sometimes he will get hit and sick but then he will get well and stand up again meaning he will not give up. Moreover, I also believe Jim is teaching Huck how the world of society works by mentioning that one day he will marry a poor girl and let go of the rich girl because that is how society works: wealthy people with wealthy people and poor people with poor people. To conclude this dialogue tells us about the character Jim that she is a realistic and thoughtful person.
