Control, part 1

So my job as a temporary administrative assistant requires that I work with a variety of people. In particular, a person I've met in the last week or so has gone beyond my usual expectations in attempting to control things. Dates, pieces of paper, meetings, information, etc. The goal is to lose nothing.

I know about myself that I have a tendency to be much more laid back most of the time, so this personality is hard for me to relate to, on a certain level. I just don't have that kind of comprehensive interest in every single possible detail. Even though I know that technically that's probably my job.

(I attempt to manage details with automatic systems--little notes and triggers--instead of relying on my faulty memory.)

The point, though, is that this person is dedicating tremendous energy to control, and it has set me to thinking about my own interest in control. What things do I want to control? When is it better to acknowledge a lack of control?
