what is the significance of eat your eggs

When Walter begins to talk about his liquor store investment, she responds, "Eat your eggs." When he says how disappointed he is that he can only tell his ten-year-old son stories about rich white people, Ruth again responds, "Eat your eggs." After Walter explodes, Ruth explains:

Honey, you never say nothing new. I listen to you every day, every night and every morning, and you never say nothing new. (shrugging) So you would rather be Mr. Arnold than be his chauffeur. So-I would rather be living in Buckingham Palace.

I don't think Aslan answered the specific question...

The signifigance of eat your eggs is that Ruth isn't supporting Walter in his investment of the liquor store.She doesn't think it is practical for a black man to achieve such a money costing dream. She doesn't believe that Walter can be successful in this and doesn't want him to get "ahead of himself."

Exactly Joe.
