* I like to stay open to respond to whatever happens. -- not sure
* I appear to be loose and casual. I like to keep plans to a minimum. YES, with plans, but I think it's because I don't want to be forced to be social when I'm not in the mood. I make plans with low-maintenance people (family, SO, a very very close friend, sometimes) but not with anyone else, ever, unless my back is against a wall. This includes plans to talk on the phone as well, though I'm on the phone a lot.
* I like to approach work as play or mix work and play. -- nope; work is work.
* I work in bursts of energy. -- sometimes, but usually I work for long periods of time.
* I am stimulated by an approaching deadline. -- no, I'm overwhelmed by it and hate it. I prefer to structure my time to avoid that crunch.
* Sometimes I stay open to new information so long I miss making decisions when they are needed. -- Never.
