Question! please help How does the shepherd archetype of Santiago develop meaning in The Alchemist?

1. He guards his herd from danger, which allows him to realize his dream of being a hero.

2. He is the keeper of the flock, so he chooses to remain loyal to his flock despite his own personal ambitions.

3. He leads his sheep to the best pastures, which allows him to fulfill his responsibilities while still satisfying his desire to travel.

4. He wants what is best for his followers, so he sells his sheep to his friend and they lead happier lives.
