"Aim high" has neither the previous sentence nor the standard next sentence.
This sentence comes from Zhuge Liang's Collection of Commandments and Exogenous Books: "The husband's ambition should be lofty, and he should admire the sages, abandon lust, abandon doubt and stagnation, so that the ambition of ordinary people can be revealed and felt sorrowfully."
