A good way to get a feel for the Stop/Start dynamic in Change Main Characters is to picture the Stop character as having a chip on its shoulder and the Start character as having a hole in its heart. .

If the actions or decisions taken by the character are what make the problem worse, then it needs to Stop

If the problem worsens because the character fails to take certain obvious actions or decisions, then it needs to Start.

A way to get a feel for the Stop/Start dynamic in Steadfast Main Characters is to picture the Stop character as being pressured to give in, and the Start character as being pressured to give up..

If you want to tell a story about a Main Character concerned with ending something bad, use a Stop Main Character

If you want to tell a story about a Main Character concerned with beginning something good, use a Start Main Character.
