My answer is to suggest how someone with IH might start to think about a vocation change, by sharing my experience. Given the nature of IH, it has been very helpful for me to shift my focus to endeavors and activities that I can do myself, pretty much in solitude. Previously, I was a co-owner and creative director of a small graphic design studio. "Solitude" is not at all objectionable to me since my personality is distinctively introverted. I absolutely get my energy from the time I spend thinking, by myself. Writing has become a viable vocational activity for me. It's something that can be done whenever I am able to do it. It doesn't require much interaction with others, but when it does, that interaction is a well-defined segment of time (call it an "interview") that I can control and designate. Whatsmore, it's generally understood by most people, that writers are not as accessible as the average normal person. And if I am only able to communicate via email or other written correspondence for an extended period of time, which is very common with me, well people I deal with have no problem with that. Also, the "research" that writers are responsible for doing is in effect, a license to be eccentric, different, or even odd. (For many people that I come in contact with, being thought of as "eccentric" or even "odd" is just fine with me. It's just not possible or practical to tell my entire "IH story" to everyone I cross paths with.) For me, writing has become a very satisfying creative activity that works very well with my inability to "work well".
