The author of Aiming High is Zhuge Liang.
The sentence "Aspirations should be high and far-reaching" comes from Zhuge Liang's "Collected Works of Zhuge Liang·Book of Admonitions to Nephews". The original text is: Husband should have high aspirations and high aspirations, admire the sages, be ruthless and lustful, abandon doubts and stagnate, and make the common people's ambitions clear. There is something to be revealed, and there is something to feel compassion for; to be patient and stretch, to get rid of the small things, to consult widely, to get rid of jealousy and stinginess, even if there is flooding and retention, it will not harm the beauty, and why it will be ineffective. If one's ambition is not strong and perseverant, his mind is not generous, he will be mediocre and stagnant in the world, he will be silently tied to his emotions, and he will always remain in mediocrity.
