Write a story about a character who is amazing at reaching out to help people in need. Consider how much this sort of work calls them to do good things on behalf of those who are less fortunate. Let the emotion they feel in this (the specific sort of work they do is up to you) guide their characterization. Give this exercise fifteen minutes of your time and then read and immediately follow the directions for the second part of the exercise.
Put that character in a situation where the tables are turned. They are now the person in dire need, the person who is less fortunate. How does this affect them? What does this change in their mind? How do they reach out for help (if they do at all)? Give this portion of the exercise an additional fifteen minutes of your time.
Write it up and see what happens.
