Fat Woman had some unintended therapy. Fat Woman was learning a new technique and had to have it practised on her. Fat Woman was asked to come up with a fixed idea. This was very hard for Fat Woman as she prides herself on not being a person of fixed ideas. You are extremely unlikely to hear Fat Woman say something prejudiced or sweeping about any identifiable group. Fat Woman even tries not to have fixed ideas about individuals. What Fat Woman does have fixed ideas about is her own experiences.
Fat Woman's fixed idea was "I could never enjoy going for a run".
Fat Woman had to think of this idea, then think of the opposite idea: "I could enjoy going for a run." Fat Woman visualised starting by tying her trainers, pictured herself running with some friends, then alone running around the nearby lake, and finally arriving at the park café being applauded by her running friends. It was a nice ending to the visualisation and Fat Woman felt positive.
For some strange, unearthly reason later that day Fat Woman went for a run. It wasn't a long run, perhaps thirty metres, from the seminar room to the ladies, but Fat Woman enjoyed it. Fat Woman enjoyed the run so much that she did it several more times that day.
Fat Woman has enjoyed going for a run.
