All meaning is constructed meaning, and, to quote Shakespeare, “there’s nothing good or bad but thinking makes it so.”
We decide, collectively, and as individuals, what is positive and what is negative. We invent for ourselves, whole cloth or adopting from our elders, meaning in life, the universe, and everything.
That doesn’t mean they are without worth. The world is altered daily through the things people imagine. Money is an invention, its value existing in the collective imaginations of those who use it. Maps are not the lands they represent, but their cartography influences where people live, work, and travel. Numbers and maths are inventions— languages invented to describe the universe and its movings, but the universe moves without needing to know them…
… nevertheless, with those invented languages we orbit distant planets with artificial satellites, and create the wonderful bit of nonsense that allows us to communicate here.
We choose to find meaning in the world, and then we choose the meaning we find there. Ultimately everything else can be winnowed away, but that. I believe we have value because I choose to believe we have value, and I weigh the good of the world with the bad because I actively choose to continue to see both. It isn’t easy all the time, and it doesn’t have to be one way or the other. But it’s what I want for the world, and what I want for me.
They also say to do what you love, and you’ll never work a day in your life. They say lots of things, many of them contradictory.
I think your advice of intentionally setting aside time is wise, though. I believe that too often we take for granted that things will just happen, and also overestimate the chilling effect of “not being spontaneous”.
