The only time I fear obsessiveness is when I experience "WORRY" that doesn't seem to let up and just torments me every waking moment and then even wakes me up from sleep to have a further audience.
on a lighter note, I wouldn't mind being a bit more obsessive about housework, I am experiencing symptoms of depression and find it difficult to maintain a tidy household. For example, the carpets haven't been vacuumed for literally months. Perhaps it is obsessive avoidance of doing unpleasant tasks, not recognizing the joyous reward of a clean abode.
