Everyone likes the security of being in control of their time and their environment, but some people like predictability more than others. Guardian personalities (ESFJ, ISFJ, ESTJ and ISTJ) are hard wired to seek out situations they can control, where they do not feel any risk and where "business as usual" reigns supreme. This preference sounds great on the surface, but it has a habit of binding Sensing-Judgers in imaginary shackles that prevent them from taking on any challenge that might not be successfully overcome.
You’re telling the room: any type can do anything. Personality theory is about understanding yourself better, playing to your strengths and broadening your horizons. It was never intended to pigeonhole anyone.
On the inside, you’re thinking. How can I, someone with a preference for Introversion, train groups of people as my job? My energy comes from in-depth, one-on-one conversations, not noise-filled, overstimulating group work. I’m much happier working and spending time alone.
There's a myth that some people are creative and others aren't. This myth is perpetuated everywhere, from the world of art and literature to big business. Marketing departments employ "creatives" to come up with new ideas. Governments rely on "creative consultants" for fresh insights. Yet there's no reason why creativity should be limited to a type or a job description.
