Being an INTJ, I try to solve root causes of problems. As such I try to analytically find patterns and develop a theory then test that theory for accuracy.
Well, I'm an ENTJ, and I do the same thing. And my point with my original post is that maybe, just maybe, you're not digging far enough down to find the root of the problem. I don't know if you're depressed or not--as I said in my post, I didn't know I was until it became clear that I was.
Look, you're really smart. I'm really smart, too. I know I'm in the top 2% IQ-wise, and sometimes people do dumb shit that gets all over me. I am really quick to see patterns and make connections and figure out how things work and how to get to the end. But then I remember that while I may have talents and abilities, others have different talents and abilities, so I try to appreciate people where they're at. And you know, sometimes it's really, really hard.
Even more important than IQ is EQ--emotional intelligence. A person can be super smart, great at their job, but if they can't get along with people, can't deal with people, can't deal with the ups and downs of dealing with day-to-day shit and incompetence that one encounters unless they live alone in a cave and never interact with anyone in person, over the phone, or online, they are not going to be successful in life. Or if they are successful (depending on the definition of success) they still may not be happy.
You can get a job on the technical side, or the management side, or go into Human Resources, or be a financial planner, or whatever else, but unless you can figure out a way to live and work with other people, you're probably not going to be very content. I used to have a poster in my office reminding me that "The common element in all your bad relationships is you." Meaning: what did I do to contribute to the situation to make it worse? And I had to be honest--sometimes it really was me and how I dealt with people.
