What do the words “eat your eggs” symbolize in a raisin in the sun

This phrase appears early in the play, as an instruction from Ruth to Walter to quiet him. Walter then employs the phrase to illustrate how women keep men from achieving their goals—every time a man gets excited about something, he claims, a woman tries to temper his enthusiasm by telling him to eat his eggs. Being quiet and eating one’s eggs represents an acceptance of the adversity that Walter and the rest of the Youngers face in life. Walter believes that Ruth, who is making his eggs, keeps him from achieving his dream, and he argues that she should be more supportive of him. The eggs she makes every day symbolize her mechanical approach to supporting him. She provides him with nourishment, but always in the same, predictable way.
