...I have the constant problem of being unable to fully articulate my views. It isn't because my views are not fully developed to any extent, it mostly has to due to the fact that I'm an Introverted Intuitive, and Ni by nature is not something that can be fully expressed through words.
Not only that, as I mentioned elsewhere, Ni is all about Meta-perspective - seeing things from a full perspective. When you see things from the "50,000 ft." perspective, there's simply too much to describe and explain to somebody else. You literally have to see it for yourself to believe it. Bluewing in his INFJ profile mentioned that INFJs are often overwhelmed by the myriad of ideas that flow through their minds.
To add on to that, Ni is very random and irrational. The insights it provides don't come readily, and only appear momentarily. So only for short, but very intense, periods at a time can I ever articulate my views to a great extent. Unfortunately, too often right when I'm the middle of articulation, my mind literally goes blank.
Which in the end gives the impression of my thoughts being rather fragmentary in nature. The reality behind the actual words is far different, there's literally an entire universe other people simply don't see.
