I mean, there is no meaning in nature, it was man who invented it, and often it appeared because of a scarcity, for example, the point is in a beautiful woman, because you are unlikely to find another one as beautiful, right?, or can you find a person who will support you and accept you as you are, like your loved ones? The examples are not the best, but I hope you get the idea.
In addition, I will say that about a year ago I watched the film "The Seventh Seal", and now sometimes I feel in the place of a character named Antonius Block. I dismissed the inevitable by refraining from suicide as a teenager, thinking I could find the meaning of life, but what was to be expected, nothing worked out. But especially now, how shall I put it... in the age of AI, it is impossible to escape the truth, self-deception no longer works, at least for me personally.
Chess Game with Death:
Much more chill than I did when I was under the impression that I had a grand scheme laid out for me.
There's a metal song by Parkway Drive called "Horizons". I'm sure the "actual" or intended meaning is different than my takeaway, but my interpretation of its message is that it's unhealthy or detrimental to believe that life has a meaning, that you're meant to leave this huge lasting impression ("masochistic / to think this would be remembered / sadistic / perpetuation of stagnation" "the marks I've left upon this world / will wash away in time")
The lyrics can sound pessimistic or depressing, but as with a lot of metal the tone and melody help set the mood. The song begins sad sounding, but ends with a sound of more blissful acceptance.
Tl;dr: worrying about what your purpose is in life will only help to assure you live a less meaningful life than we are already all destined to live.
