I found this under Storyforming > MC Problem, which also says
Even though the Problem is what is "wrong" with the Main Character according to the outside world, if the Main Character is actually correct in its motives and the world at large is mistaken, then this "Problem" is what drives the Main Character to set things right.
In my case, the world says "You should take more risks/face your fears" and MC says "I can't! Bad things might happen to others/me" and/or "Even if you're right, I'm too much a coward." By the end, MC Changes and it's Good-- "My fears were exaggerated" and "I am stronger than I'd thought."
I'm not sure whether to emphasize lack of confidence, lack of risk-taking, or avoiding fears.
Of course, it might fail in the attempt, but its heart is in the right place. On the other hand, the Main Character might be mistaken, and its Problem is just that: the source of all the story's difficulties.
So, there are really two ways to look at the Main Character's Problem.
Which is right for your story? That is determined by your answers to two of the 12 Essential Questions: Success/Failure and Good/Bad.
However, in the Success/Bad and Failure/Good stories, the author's message is that the Main Character was actually the cause of everyone's problems and therefore, what drove him was really the source of the inequity.
In this case, the Main Character Problem really IS a Problem, and needed to be solved.
Then MC Solution says this:
Do you see your Main Character as having the Problem or solving the Problem?
If he has the problem, then arriving at the Main Character's Solution is what the story is all about.
But if he is solving the problem, the Main Character's Solution is the one thing he must avoid at all costs.
If my MC has an MC Problem about being too cautious but gains confidence and learns to take chances by the end (Good) and the OS Succeeds (say everyone wants a sense of belonging, which was something going on before MC enters the picture, but MC's problem may thwart their latest attempts to solve it. Perhaps MC's insight helps something or they find that trying to deal with MC has brought them all together into their own group), how does that fit in?
