This thread is very consistent with the personal development theories of good (cognitive functions-based) Myers-Briggs practitioners. In particular, check out
this page on the importance of developing your "co-pilot" function (i.e., creative function). Also check out
this page on developing your "10-year-old" function (i.e., mobilizing function). It notes that your mobilizing function is wonderful for growth, but ONLY IF your creative is already very good! Skipping use of your creative to just go between your base and mobilizing (what Myers-Briggs calls "tertiary loops") results in immature use of your mobilizing and hinders growth.
I'm quite a fan of this
"cheat sheet" for personal growth (remember that the last letter is switched for introverts, between Socionics and Myers-Briggs), which provides examples of how each type can jumpstart their development.
I think the theory of "personal growth through creative function development" matches what I've observed myself/my friends of various types needing to do in order to break out of a rut and progress in our goals/life/attainment of fulfillment/happiness. For example, I know an LSE whose anxiety is relieved when he masters the details of various tools for his work, and another LSE who claims not to "get" any activity (like dancing) unless he learns it himself and understands why certain things are done during it. I know an ILI whose life is stagnant because he keeps reading, reading, reading, but he hasn't put any effort into actually implementing any of his grand ideas for society. My EII friends and I are at our best when we are getting out and doing new things rather than wallowing in the difference between reality and what we want; it helps us be less fearful of losing what we have.
Developing your mobilizing function is probably vvv helpful for becoming a superstar in your field, but it doesn't seem like anyone can skip the step of developing his creative first/I'm not sure everyone has the ability to develop his mobilizing in a healthy way.
