If you have taken a Psych 100 level class, then you know of Maslow's hierarchy of needs. That each needs to be met to continue up the pyramid until you achieve self-actualization (and presumably happiness). I found this great article on the hierarchy of CREATIVE needs by Ariel Gross.
While not perfect, this fits pretty well with my experience. I am currently struggling between work and wonder while rarely achieving wisdom by helping others at group shoots.
