Internal

Memorable stories reflect internal change or an emotional realisation.

Stories that simply recount events, or describe ‘what happened’, might be interesting and entertaining, but the great ones illustrate change.   This does not mean that great events or startling action need to have occurred: those stories may be entertaining but if there is no difference between before and after, then they are just an anecdote.  With anecdotes, the listener likely won’t be moved, nor their view changed, and they won’t feel more connected to you.  Stories worth telling are those where something has changed internally, not out there in the world.
