Interpretation: A gentleman's trip is to meditate on himself, to economize on Xiu De, to be indifferent but unable to be clear-minded, and to be far-sighted without quietness.
Summarized as:
1, improve your self-cultivation from tranquility.
2. Diligence and self-cultivation.
If you don't want to be quiet, you can't be clear about your ambitions, and you can't achieve your lofty goals without excluding external interference. Learning must be calm and single-minded, and talent comes from learning. Therefore, if you don't study, you won't grow up, and if you don't have ambition, you won't get results.
You can't cheer up if you are addicted to laziness, and impatience and adventure can't cultivate your temperament. Time flies, and the will passes with the years. In the end, they were all destroyed, and most of them were uncontested and not used by society. They can only sit in the poor house sadly. How can they regret it at that time?

This article was written by Zhuge Liang to his eight-year-old son, Zhuge Zhan, in the 12th year of Jian Xing in Shu Han Dynasty (234). Zhuge Liang dedicated his life to the country and died. He worked day and night for the national cause of Shu and Han and neglected to educate his son personally, so he wrote this letter to warn Zhuge Zhan.
The virtue of a gentleman should be (should be) quiet to cultivate one's morality, and frugal to cultivate one's morality. If you don't take fame and fortune lightly, you can't be clear about your ambitions, and you can't achieve lofty goals without calming your heart.
Learning must be quiet, and knowledge needs to be learned. You can't broaden your knowledge if you don't study, and you can't succeed if you don't make up your mind to study. You can't strive for progress if you are addicted to procrastination, and you can't refine your temperament if you are paranoid and impetuous. As the years fly by, the will fades day by day, so it gradually withers, and most of them can't integrate into society, sadly guarding the poor home. It will be too late (regret)!
