inverse arrogance?

I have this not-fully-fleshed thought this morning/afternoon/whatever... want to explore it.

we call those who are demonstrably self-centered, who speak and act primarily for and about themselves, who demonstrate a belief that their actions and thoughts impact the world: ARROGANT.

is there a term for people who seem to believe that only OTHER people matter? Edit: in a wildly unrealistic or drastically misplaced humility, only other people's thoughts, actions, beliefs matter? Or is that also ARROGANT and SELF-CENTERED, only in a backwards, skewed, or mirror-universe kind of way?

Recently reflecting on my thoughts around the end of the Drama/Reading teaching job... and I recall at some point believing that I didn't need to tell the (drama) students that I wasn't coming back next year... because they'd have a better Drama teacher next year? I know I was rationalizing. I knew it then.

I know to some degree, I decided not to share because it make it be awkward, difficult to do the job... but there was also a touch of "because I didn't matter"...

On one level, I know I did matter. I had students hug and confide in me; I stayed late and sometimes came early to facilitate the things the students were passionate about, I was learning to be an advocate for them.

and yet, I was convinced that me leaving wouldn't matter to them, to the office, to my department...

was it an intellectual conceit to protect my own feelings or to make the perceived emotional impact of my leaving less?
was it a derelict remainder from my years of low self-esteem?

Five summers ago, I expressed shock and amazement when Jeff (we had just started dating) downloaded both Evanescence albums because I was enthusiastic about them; I had just heard one album in its entirety for the first time.

He held my hand and caught my eyes and said, "You know, you have an IMPACT. What you know, what you like, it makes an impression on people."

That blew me away.

Sat there, flummoxed, (and probably crying), trying to assimilate the concept.

I still am made of fail with regards to incorporating this into my life.
Of course, if what I do (or don't do) doesn't matter, there are all sorts of corollaries.

Like, I don't have to work too hard. No one will care.
a whole other bunch of don't have to's follow, of course, (fill in the blanks yourself, you're imaginative people (see, there I go again))

but those don't have to's get blown away if I have made a commitment to live an ethical lifestyle. For me.

Regardless of the impact I believe I have on the world (which =! my actual impact on the world, I know), if I'm living an ethical life, there's the one undeniable reason to follow up on my promises, to work hard and well, to try hard, to work toward personal growth,
For me.
Because it's the right thing to do.

I joke about being a solipsist. I think I need to examine what parts of that notion are valid and workable and which I need to discard.

and maybe in this regard I'm coming at the question ass backwards, I matter because I'm ethical, but until I finish up a bunch of other healing work I think that is the best, clearest path for me to walk, to arrive at the conclusion that I matter.
