Less isn’t always more. Meaningless work or activities don’t contribute to anything. Deliberately pursuing meaningless activities, albeit temporarily, does fulfill a purpose. They might help to relax. Structural and prolonged meaningless activities, on the other hand, don’t really fulfill a purpose.
If it were possible for meaningfulness to be expressed on a scale, having a job with the maximum amount of meaningfulness might be unattainable.
What is, however attainable is, trying to maximize meaningfulness and increasing it day by day.
