Man cannot be worse than he is, because it is impossible to be worse than he is. Your disappointment or fascination with people speaks to your stupidity, you know nothing about people or yourself.
Disappointment is often associated with charm. You first create idols for yourself, and then you realize that your idols are no better than their Creator.
Frustration is the fear of losing again. Frustration is cowardice. Man is afraid of pain... "Again I will hurt you" - going through his subconscious. "I'd better not do anything,"thinks the horse," and that will save me from another disappointment."
The more people relax and have fun, the more he is disappointed in life. The meaninglessness of life is excruciating, trying to find solace in entertainment, a person plunges deeper and deeper into the quagmire of depression.
