Answer:
He wanted to travel the world
Step-by-step explanation:
Santiago became a shepherd because he wanted to travel. His father told him that only rich people and shepherds were able to travel. Santiago has been a shepherd for two years. As a shepherd, he is a nomad. He can go from place to place, and never settles down. Santiago is unusual for a shepherd because he is too young and doesn't know too much to be a Shepherd.
