P.S. I haven't found a meaning in life for myself; I don't know what it is for others (although, why not? You can read about it).
...some people don't find a meaning in life, and even at the end of their lives. Some define it quite early, but probably most people simply have an intermediate meaning for each period of their life. As a person overcomes another age-related period or changes their status in society, they automatically restructure their concepts, priorities, and attitude towards the past/present/future... principles and goals appear or disappear... and so on.
Perhaps the meaning of life is to achieve harmony! That is, to ensure that everything desired coincides with reality at each stage of life, every day, every hour... and since each person has their own quirks, the meaning of life should also be different, but most often people identify the same priorities, such as: "the meaning of life is children, family, wealth, the future, etc."... but this is just a template, and most lives unfold in this way:
And sometimes, certain periods from the template shift or change places, or are completely absent....
I've now come to the conclusion that everything is much simpler:
the meaning of life is to live! :)
