I had the same thing. It's me almost to a "T". Freaky shit.
Why is it freaky?
Let's break it down:
Though quiet on the outside,
I don't think many people would consider themselves "noisy on the outside." Even someone who blabs all day long still has quiet periods, so there is something to cue in on as a match.
you are often the hidden hero;
No normal person considers themselves to always be in the forefront of everyone's thoughts 24/7. So we are "hidden" unless we step onto their stage.
"Hero" is especially vague modified by "hidden". Basically any action which may result in any social acceptance touches on the term. With "hidden" it concentrates on solely
your perception, so just the internal loop that pushes social acceptance behavior will trigger a match.
someone who rushes in when needed and then after the emergency is over fades back into the woodwork.
We like to be needed. It places us in a position of power.
The phrase "after the emergency is over" defines a boundary (and one that the reader is defining). So, reduced, it says, "After 'boundary', you return to normal." Duh. Of course a self-assessed boundary is going to precede a return to normalcy. That is why it is internally defined as "a return to normalcy." If there was no boundary there would be no differentiation.
Because of this sense of duty and honor, you can also on occasion be rigid in your viewpoint and unyielding in the face of other ways of thinking.
As opposed to what? "You have no sense of responsibility and you instantly believe anything that anyone tells you -- even if it contradicts what the person right before you told you"?
Usually cynical and rarely trusting of others,
There's a reason "gullible" isn't in the dictionary.
you maintain a small set of intimate friends.
"Intimate" is pretty much "small" by definition. You would define something that you would share with a large crowd to be "not intimate."
These bonds are stronger than most.
How would an intimate bond be weaker than most?
You are always grounded in the present moment.
As opposed to not knowing where you are?
If you can make factual statements about your current self, you are "grounded in the present moment." And it's pretty hard not to be able to make statements about your current self.
Your close bonds can also lead to clique-ishness
Wow, amazing how accurately the word "cliquish" describes a clique.
and a tendency to gossip about those who are deemed less worthy.
That positioning is pretty much in the definition of "gossip." Gossip about those who are deemed more worthy is called, "complimenting," or, "fawning."
You are an integrative thinker, collecting data from a wide range of sources and applying it to your worldview.
Of course you integrate everything that you self-assess as pertinent. Even drooling Fox News viewers who reject anything contrary as "elitist" and "liberally biased" are going to answer in the affirmative to this because their narrow minds aren't self-assessed as narrow. That requires a wider perspective than they have.
You can become overly task-oriented.
What is a "task?" Again, a grouping allowed to be self-defined.
In stressful situations you often withdraw from the world to seek peace in contemplation.
Most situations don't allow for the "fight" in "fight or flight." So "flight" is standard.
You often seem cold and withdrawn.
Who is never moody? Who absolutely never squeaks to get a little grease?
Often you will withdraw rather than verbalize your discontent.
Nobody likes a completely self-centered whiner. And part of friendship is letting your friends have their turn, and taking enjoyment in that even if there's a little personal discontent that today's action isn't all about you.
