My Fi gets overactive sometimes and when that happens, Se sees every little thing wrong that's going on and tattles to Ni who starts concluding to the worst scenario. This makes me feel crappy so Te tries to find a friend to confide to. At the end of the day, I look like an INFJ.
Sometimes, Se notices a lot of options and Ni with Te draw hundreds of different viable conclusions from all the choices available. This gets me excited and I look like an ENTP.
When something really needs to get done, I assert myself a little more and swing towards Te rather than Ni. It looks like ENTJ but actually I get tired from doing that for too long.
I'm just me, probably an INTJ, but it's not the end of the world if I'm actually an ENFP.
