In time you will learn to control your powers...
From experience, I'd say keep doing what you are interested in and keep learning new things. You'll probably need one job you stick with for a bit just so have experience in something and you look employable. After that people tend to respect the crazy mix of things you've learnt along the way. At the same time, I regret not taking more jobs when I was younger just so I could look back on the experience.
Regarding the parameters part, these days I figure if I don't intuitively see it then I'm missing information so search for it. I've got stuck in endless possibilities less as I've got older. Some of it was anxiety rather than anything to do with my personality type.
Most of the time I ground my intuition by logically ordering things on the page so I can assess them, almost like a feedback loop, and I listen to that feeling certain things are important or not quite right.
I can tell you what I do by private message, if you are interested.
