About writing: Hmmm...I don't really "do" anything to get to a place where I'm ready to write or be submersed in that other world.
When I write I sit down at the keyboard and the world around me ceases to exist for the most part; it is like I am a water hose and the stuff I'm writing is being transported from this other place and I'm just recording it, like how water flows from a distant source through a water hose. I have this movie playing in my head and I am just trying to type it as fast as it plays in my mind. I don't do anything to prepare. I just sit down and bam! There it is...a scene from a story and when I'm driving down the road, sometimes I'm seeing this story in my head and hearing the characters talk. I don't even feel like it's really me creating the stories. I'm just "reporting" them.
It's kind of hard to explain but maybe you get it. Maybe you have the same thing happen sometimes. I mean after all, don't ESTPs share the same functions in reverse order and if that is the case then maybe listening to music is the way you tap into the Ni which I think is the culprit in much story writing. It's like it's collected all of this info that I didn't even know I knew and suddenly there's this whole other world created and I just have to tell about it. However, on the other hand, when I'm getting ready to do something that is very much in the here and now, I have to "psyche myself up" first. Like if I'm going to do a rappel down the face of a cliff or a free hang or if I'm going to put on a show, I have to do a bunch of physical stuff to get me rooted in the moment, so I can let go. I have to somehow release all kinds of mental tension. So maybe that's me drumming up my Se because maybe it's like your Ni and it needs a little help sometimes.
EDIT: Oh, and about this question:You just have to be who you are and do what works for you. It could be that the puddle on the skyscraper is a universe all in and of itself. Who's to say? Maybe each type, and each person for that matter, has his or her own whole other realm.So my question is, am I just wading feet deep into a puddle on the roof of a skyscraper? Is there a whole other realm I haven't journeyed into yet that I'm missing out on?
