What does it mean that the heart is higher than the sky and life is thinner than paper?

My heart is higher than the sky, and my life is thinner than paper, which means that although I have great ambitions, my life is too frivolous-I can't die on my own, I was born in poverty, and I can't display my ambitions, so I am humble to death. From A Dream of Red Mansions. The original text is: the heart is higher than the sky, as a humble, romantic and intelligent person. Immortality begets slander, and amorous childe is empty.

There is always a gap between ideal and reality. When this gap reaches a world of difference, then this so-called ideal becomes fantasy and delusion. When a person's inner imagination and the goal he wants to achieve are far from his actual ability and real conditions, it will not only lead to disappointment, but also delay and waste everything in reality.

No matter how much we yearn for our feelings, we have to face up to a basic fact that life is a chicken feather. At the same time, boredom, boredom and nothingness, like the plague, always accompany our lives and never leave.

Man's destiny is in his own hands, and its quality depends on his own management. If you hold those irrelevant ideas all day and can't live a down-to-earth life, your fate will naturally be very bad. This is the reason why the heart is higher than the sky and life is thinner than paper.
