Something that occurred to me after a recent session was the usefulness of impossible goals. Something to keep in mind is that often it is just as good to have a Fate Point as a Persona Point.
If you’re rolling six dice or more, a Fate Point will on average get you more than an extra die. Plus, you can choose whether to spend it after the roll. Of course, Persona Points do let you add in your Nature, at the cost of taxing your Nature - but often you don’t want that risk. So it can be totally worthwhile to set goals for yourself that are impossible or nearly so.
