Answer:
He learned not to forget who you are
Explanation:
"The main protagonist, Jim Hawkins, faces serious, even vital life challenges at a very young age. Yet, he manages to bear everything life threw at him and became a better person than he used to be. Being tempted by John Silver with treasure, luxury and fame, Jim rejects all of it, instead coming back and saving his friends. The young boy shows as much courage and strong spirit (and maybe even more) as grown-up and experienced men, because he never forgets who he is and what is really important in life. Not gold, jewelry or pirate’s fame, but honor, true friendship and being true to yourself. "

Jim learned the lesson of valuing what really mattered to him, and to place importance in the life of others (selflessness). When John Silver offered him many riches in order to get him to cooperate, Jim was almost tempted. But in the end, he denied all of it, and fought till the end to save his friends.
