What motivates people to do something? Because there is something in it for them. Which sounds selfish, but it's true. Even good deeds make us feel good, useful, helpful... so we get some positive reinforcement out of the experience and maybe want to keep helping others.
But for a set of interesting characters, just doing good deeds for the joy of helping others is not exactly compelling novel material.
Can you tell I'm stuck trying to plot character motivations?
One of them can just be in it to help her friend. But the others? Are practically, if not entirely, strangers. What will each of them get out of helping someone on their quest?
Pondering, pondering, pondering...
Feel free to share any suggestions. Really, folks! :)
