Wow Ritella, that's pretty brave of you to post a video of yourself on here. I have to say that it was interesting to watch it though, especially since I am also INFj. You seem very talkative which I can't relate to at all because I am generally pretty quiet and would feel very uncomfortable giving a long talk like that in front of a webcam! However, I dont necessarily think that talkativeness is always related to type, but I do think it is interesting to see how different I am from other INFj's.
In that video, you sort of reminded me of an ENFj I know, although judging by all your posts I have read, I think you are INFj. Also, you really seem to use facial expressions to convey your feelings a lot, and I feel that I do the same thing. I often feel that people can read me well because my face gives things away (unless i am really trying to hide my feelings, and in that case i can be pretty successful at it).
