"And I, uh, I wonder how anybody can think his personality changes with his success. I've had quite a bit of success but I feel that I'm just the same person as I always was"

Rube Goldberg's quote talks with the idea that success does not necessarily transform an individual's core personality. He suggests that regardless of his own success, he still feels like the exact same person he constantly was. This suggests that he believes success does not necessarily result in a change in one's personality or values. He is recommending that success does not always cause an individual becoming more arrogant or self-indulgent. Rather, he believes that an individual's core character continues to be the same despite their success. This quote talks to the idea that success does not always bring about a modification in one's character or worths, which a person's core character stays the same regardless of their success.
