Working definitions are very helpful in training children how those biblical character traits play out in their daily lives. You can tell your child to use self-control until you are blue in the face, but unless they truly understand and reminded of the meaning a 100 times, they won't really know what you are asking of them.
Here are some working definitions for sensitivity and self-control I read in a parenting newsletter about how to handle it when children are annoying from National Center for Biblical Counseling :
Self-control is the ability to control myself so that don't have to.
Self-control means to think before I act.
Self-control is the ability to talk about problems instead of grabbing, pushing, or hitting.
Self-control means that I limit the noises I make when others are around.
Self-control means that I focus on one thing until it gets done, before I move to the next.
Sensitivity means that when I walk into a room I look and listen before I speak.
Sensitivity is thinking about how my actions are affecting other people.
Sensitivity means thinking about how I could help someone else.
