People here misunderstand ESTps. Badly. So I'm going to clear things up. I'll use myself as an example, and I'll be general enough so that what I say fits other ESTps, rather than just myself. I'll start with the basics, then get more in-depth.
We see everything through our base function (duh). Whether it be noticing the things that are there around us, being active, or interacting with others, is what drives us through our daily lives.
When I'm living my life, I don't really sit back to analyze things; I just do whatever it is I'm doing. I find that I'm the happiest when I'm active, whether it be by myself or with others, rather than sitting in a circle, talking about my feelings towards other people. A quote that I heard another ESTp say: "Do something." If there is something that I want to do, I'd rather just go and do it, rather than wasting time analyzing whether I should or shouldn't do it, and by what means. Inactivity is paralyzing for us. Inactivity usually includes sitting around and doing nothing, when there are obvious, more fun things that I could easily be doing at the moment. For example, even though I am sitting in a chair right now, I am still doing something, as my fingers are moving rapidly across my keyboard. Because I'm sick of people making shallow judgements about me, I'm doing something about it right now, in the form of creating this post. Usually, I prefer more active things than this, though. If I get bored of this and think of something better to do, I'll stop typing this, and go do whatever that is. Sports are a good activity, because they're active, provide excercise, and possibly competition depending on the sport, and are an easy way to channel off any excess that I might have.
Usually, I am not processing words through my head, but rather, I'm just noticing everything that I can, and deciding whether I should do anything with this newly aquired information. For example, I turn around, and I see a bright red jacket. I don't think, "Oh, that jacket is red. I like red." Instead, I see the red, get happy, then move on in life. The same thing goes when I'm making decisions. I'll sort of visualize things, but not actually thinking, "I should do that, rather than that. That would make more sense." Instead, I get sort of a vague sense that one might be better than the other, and I act on it. I don't really like to analyze things any deeper than that. It just seems unnescessary, and a waste of time, when I could be doing something more interesting and rewarding instead.
When interacting with people, I usually have confidence of steel. Over the years, we've learned that people don't treat pansies well, and that we shouldn't act like one, even if we're feeling like one. Like if I'm ever nervous about something, and I tell a friend, they usually respond with something along the lines of, "Really? It doesn't seem like that at all." We use this to our greatest advantage, and this really helps us get what we want, and ignore any nervousness that we might be feeling. See
this thread for more info on how we can trick ourselves into feeling things. That general principal still applies in the scenario above.
I highly suggest you check out that thread (if you haven't already) for more info on how ESTps think, because I don't have the time to type it all out here again.
