The sort of stuff you talk about here, I'm already very good at. I've been "accused of" being ENTJ because of that.
Not that I care enough to tinker with building things with my own two hands as in the example but otherwise yes, I'm able to easily find things in the environment that I need for my more short term or immediate goals, put steps together and execute them.
As for the "internal web of concepts", I guess I don't see the above process as such in my own case but then this expression is pretty generic and so in a way it may apply but I build a lot of this sort of stuff as I go. Only a bit of it is available as a pre-planned something. It's due to impatience, mainly. And that is what would go against ENxJ typing.
Well thanksLife improvement is cool stuff.
I've put a lot of effort into self discovery and self improvement over the last five years, and it has paid off in so many ways.
It has been a humbling experience in many ways, but also very rewarding.
The work is not always easy, and can simply be frustrating at times, but anything worth accomplishing is rarely easy to do.
Good luck and please keep in touch!
