So what is the point of doing many things?

Maybe it doesn't need a purpose in the first place.
Then why bother assigning meaning?
Perhaps there's no need to give it too much significance.
Treat it as a harmonious home where you can coexist peacefully.
When you're not around, it still goes on living its life.
When you return, it will be ready and waiting for you.
You can't always keep your eyes on it; any detail will be infinitely magnified if you keep staring.
