Even if I am a Multipotentialite, not all my interests are equally valuable to me. Some are more valuable than others by virtue of their proximity to my purpose. This is one of the ways that purpose organizes your life. It creates a hierarchy of interests (here is My current hierarchy of interests).
Since my purpose statement all my interests are organized based on their proximity to the realization of that purpose. My Primary interests helps me experience Ginhawa more directly than my Secondary interests. Secondary interests help create the ideal environments, physical states, and mental states that allow me to experience Ginhawa.
