The term dimensions of wellness comes from the field of public health, with the recognition that each part of life impacts the others, and goals in one area are hindered or helped by other areas. Psychotherapist Allen Wheelis, in How People Change, describes a gradual upward spiral as a way we make progress, which fits with the idea that as you master the basics in various areas, each new habit or accomplishment can support further development in the other life goals important to you.
If the idea of making and tracking goals gives you hives, skip that, but poke around to see if the podcast lists introduce you to an interesting new author or concept. See also the "Recommended" tab for more podcasts.
