Well it does not have to be pulled straight from the book so-to-speak but listing things as Traits, Ideals, Bonds, and Flaws helps me at least understand how you envision it as part of you character. Thus helping to remove some of the guesswork for me.
Next back to the straight from the book -- your Traits (2+), Ideals (1+), Bonds (1+), and Flaws (1+) can be reworded in any fashion you choose as long as the basic understanding of what it does is fairly easy to apply. Thus you can use the books version as examples of how to write one of your own which I have done on occasion. Also keep in mind these Personality Aspects are what we are going to use to fuel your Inspiration Bank so the more of them you have not only helps to better define your character but also helps to make it easier to gain Inspiration Points. I usually have a minimum of 2 of everything but sometimes I have had as many as 5. It all depends on what you feel fits the personality profile you want to in-act as part of your character.
