Okay, I skipped to the end without reading other posts, like you asked. Here are a few qualities that help me to be well-suited for this job. Good design sense and good people sense. Needing variety in order to stay engaged with my job. This is why, although in school I was one of the most 'intellectual' people, the thought of a desk or academic job just feels like a slow suffocating death. I need a lot of new things to happen, to see new things, and to interact with many people in meaningful ways. Which is strange for an introvert, I suppose, but that's how it is. All the art that comes in, and the interesting folks who bring it, along with the chance to create design treatments, meets all these needs in my way of functioning.
Also, these are all short term, concrete tasks, not like sitting at a computer working on some endless loop of a business project. Even when it was done, it wouldn't seem done to me, because the next day would be more of the same sort of thing. With this job, there's always something new and different happening. This is a job with a lot of distractions, and I'm wired to be naturally distractible, so I just make sure that whatever I'm distracted by is still productive. Looks scattered to an outsider, but I get more done than anyone else there.
Plus, a personality that values creative fulfillment and interpersonal connections over how much money I make. Granted, there are framers who make a fine living. That's great, I admire you, and you can be proud of yourselves. But most people who do this job do it for the life, not because it's lucrative. I could make more money at a lot of other jobs, but this one is pleasing in the ways that matter most to me. Forgive me, please for how long this post is.
Thanks for starting the thread. Now I'll go back and have fun reading other people's answers.
