Its also chores that have an end, that you can have mastery over, that makes for only a small amount of variation compared to all of life.
Then you also know that you don't need to do things as fast as possible, you can always let things chill. Sometimes you can use it to practice not caring about everything - like "this run, I don't fish until year 2 - just farming for me."
When I started stardew I didn't know how to play so I would spend days waking up walking around and then go back to sleep repeating until my parsnips grew, but when I introduced my SO to the game, we ended up trying to learn how to actually play and then ended up with spreadsheets to track all the seasons, grow cycles, relationships and whatever else lol
