What are 3 things that Ray achieves from finding J.D. Salinger that help him achieve his goal in the book?

The relationship between Ray and J. D. Salinger involves the things that Ray does for himself and for Salinger, as well as those that Salinger does for Ray.
Ray feels drawn to visit Salinger after hearing voices saying “Ease his pain.” He interprets this as a message that he should assist the reclusive author. After visiting Salinger, Ray takes him to a baseball game. Salinger becomes absorbed in that particular game, as well as the game in general. Encouraging this change in him, as he comes out of his self-constructed shell, is an achievement for Ray. By doing good for someone else, he does achieve his goal to “ease his pain.”
Salinger helps Ray when he comes home to Iowa with him to "see this thing through." He has an idea of how the newly constructed baseball field can bring income to Ray and his family, as well as for bringing the ghostly baseball players back to life. Achieving financial stability and being a good husband and family was one of Ray’s dreams. Salinger played an instrumental role in helping him achieve this goal, or to “fulfill his dream.”
Ray and his brother had a complicated relationship with their father. By building the field, Ray was able to reconnect with his deceased father and to help his brother repair their broken relationship. Through the field's success, Ray brings his father and brother together. Finding Salinger and broadening his own understanding of the field’s potential, Ray further eased the pain of his father and brother—something he might not have achieved had he not sought and found Salinger.
