My brother recently noted I have an uncanny ability to tune out my environment. I can be so deep into something, someone can be five feet away yelling my name and I will not break my attention. I say that because it's not that I don't notice them. I can feel a slight tug of attention in the back of my mind; I just refuse to let it interrupt my current train of thought. It is almost as if I become far disembodied, drifting around on distant planes, an outside observer to even myself. When I am forced to return, I will typically objectify a future spot I am working toward, and only once I reach it do I feel comfortable unfocusing my attention.
Reading this over, I believe my key point is the control of focus. I think of my sister, who wears ear plugs to deafen external noise. We've talked about it, and she tells me she is unable to drown out the external world on her own. Another point of reference would be the thread on being interrupted. I cannot say I've had much of the problem, because I am rarely 'interrupted'. I always finish and begin exactly where I intend.
It has its ups and downs. I can sleep nearly anywhere. I usually have a pleasurable, calm disposition despite the situation. I am moderately tempered against pain and other bodily discomforts. On the other hand, I can become easily unfocused in situations I should be. Miles can pass driving before I begin to pay attention to side streets and walkways. I once had a customer slam her items on the counter and walk out of the store because I did not explicitly inform her I was ringing her up (even though I did greet her coming into the store and when she approached the counter). Employees have tried asking me questions while I was working in my office and I would hardly acknowledge they were there. Only once I felt comfortable with my position would I turn to acknowledge them. I remember once having to follow an employee out of my office to apologize because he left in frustration.
I am wondering if it is resultant of function order. Your thoughts?
