What is the unbearable weight in life?

There are many "unbearable burdens" in a person's life, such as work, life, feelings, interpersonal relationships and so on, which vary from person to person. But people often ignore that there is "unbearable lightness" in life! There may be many reasons why a person living in a stress-free world has no pressure, such as he is pampered and well-fed; For example, he is not enterprising, doing nothing all day, like a walking corpse; For example, he escapes from reality, sees through the world of mortals and escapes into an empty door ... these are all negative ways of doing things. This "stress-free" life will not make people feel "heavy" but "relaxed", but this kind of "relaxed" will ruin a person, drown him in the world of mortals and accomplish nothing. Therefore, this kind of "lightness" is unacceptable, and it should not be borne in life, and it cannot be borne!
