If you are good at thinking, this skill is applicable in two domains only: mathematics and logic.
Interesting idea. FYI, mathematics and logic used in business, physics, chemistry, electronics, data analysis, biology, economics, business, accounting, pricing, calculating profit margins, and even dating (lots of dating sites now rely on complex mathematical calculations to pick a better choice of mate. The algorithms are being improved. So it appears that the only problem with this approach is that it was only started recently). There's almost no area of life that has not been so improved by the addition of mathematics, that in almost every case where it was applied successfully, it's become the de facto standard that everyone uses in those fields.
Everything else is heuristics, rules of thumb, experience, trial and error.
These are all good techniques. Mathematics is called the Queen of the Sciences. The other sciences are the scientific study of a particular topic. Mathematics is the scientific study of the rules that the other sciences use. Heuristics, rules of thumb, experience, trial and error, and much, much more are studied scientifically in mathematics. If one knows physics, one understands the physical very well. If one knows mathematics, one knows how to use heuristics, rules of thumb, experience, trial and error, and much, much, much more, in millions of situations, that even those highly experienced with such techniques never dreamt were possible.
How do I find the right job? How do I find a girl? Why do I have social anxiety?
These are not questions of theory, they are questions of trial and error. The solution is simple: get out of the comfortable sphere of theorizing inside your head. Let go of the arrogant trust in your ability to "think" and theorize. Think less. Test the limits of experience.

That works for TJs, as they use Te, which is an extraverted function. Extraverted functions tend to be big on action, and low on computation. That doesn't work with Ti, because Ti is high on computation. Trying to get Ti to work like Te, is like trying to drive to the local supermarket in a jet plane. It goes so fast, that you just fly by. It takes a dozen tries just to get it within a mile. Plus, trying to achieve consciously, results in the conscious self trying to take over the jobs of the unconscious, which tends to produce a role-reversal, resulting in the subconscious doing jobs that it is poor at, and the conscious doing jobs that it is poor at.
INTPs tend to be productive, when they keep themselves in a state of calm, and focus on the things that interest them, letting their subconscious accomplish for them automatically. Going out to achieve uses Fi, which is very low down in an INTP's stack. INTPs get on better by using their Fe as a motivator, going out with a friend who wants a wing-man, and talking to people who seem like they could do with cheering up, and using their Ti to analyse human behavioural patterns. By default, the subconscious Si & Fe sends INTPs out to collect data. Ne automatically collects data on people they meet, which is where INTPs get their data for answering questions of trial and error. All INTPs have to do is ask their Ne to recall their experiences and spot the patterns.
In short, the solution is incredibly simple for INTPs: just let go, chill out, relax, and do whatever comes naturally. They're not Js. Their subconscious are Js for them.
