You’ll need a certain number of people to eat a whole elephant anyway. If you make slices small enough, at least they won’t feel sick at the end of it.
There is no overhead in the activities of choosing the piece that looks most delicious, putting it in your mouth, chewing it and swallowing it. There is some, but it definitly beats having to swallow the elephant whole.
So don’t try to be subjective or pragmatic or take a case by case approach. Don’t fool yourself.
Write small stories.
