I remember discussing midlife crisis with a local LLM. Aspirations? Making up for lost time? General dissatisfaction?
Like what old and wise people have said, it's your choice to reach success in life or to waste time, and to be dissatisfied.
Aging is natural. It's part of living. One day we'll all die. It's your choice whether people will waste time thinking about it.
Buying material goods, eh. Pretty wasteful unless it has utility.
