Into the wild

Why do you think Chris/Alex was reluctant to

take the advice of Galien?

Chris is very stubborn, he believes that he can do everything by himself. He is very hardworking, doing his best always, and he doesn't react well to critics or any kind of authority.

Explanation:

That is why he refuses advice that Gelien wanted to give him, that wanted to buy him better equipment for his trip to Alaska. He is afraid to accept any advice because he feels that those pieces of advice could stop him from going where he intended to go.
