I could agree with the term "Life is what you make it".
However, If only I can determine what happens in "my own world", then I would be a space fairing multi-billionaire with a ton of friends peace and heaven on earth and.... I take it you understand my point ;p
You have no more control over who becomes your friend than you do over the weather. That is because a very large percentage of people has no interest in befriending anyone unless it gains them something or they can use you/your skills for something. Then there is a very small percentage that is interested in befriending others that keep a limit on the amount of friends they have or simply are not interested in befriending you.
You cannot expect to be able to determine what happens in "your own world" because you don't own or control the world.
I think I mentioned it somewhere before, but I really really really struggle at making/finding/developing a friendship in person and generally I am invisible to the point where I feel like I must be the natural opposite of a charismatic person. But by all means if you got a life hack for me, let me know.
As for the OP. I wouldn't know, I don't ask everyone who tolerates my presence to take the MBTI test.
That said I find the most common ground with other introverts, and believe it or not from the rest of this post, I am usually the more positive and optimistic one
