Would you say you deal with stress well?

Usually yes. it is funny (shhhh ... don't tell this to my employer) but under stress, I'm usually extremely calm, more concise, have more energy, do things faster, find sharper ideas, give very precise direction, lose weight and look for more creative solutions to the given problem. On the flip side, when I'm stressed, I'm less likely to sugar coat everything (well, I'm from Europe anyway, so I usually get away with that excuse :)), less likely to put up with Irrelevance (in general), more likely to cut it short and get to action -- like a person on a life or death type of mission.
I act in a similar way when an idea gives me "wings" and I cannot even sleep before I turn that idea up side down, left to right, every angle, every centimeter (well, inch) -- funny isn't it? Stress & adrenaline - are best sisters.
Does this make me "best candidate for stressful situations"?

I could definitely deal with stress a little bit better. For example, this past weekend, when everyone in my house was sick, I really felt like I was pushed to the brink. I think, because of the basic complete lack of time I have for myself, the stress tends to build up. Definitely something I have to work on.

I would say that when I was in my twenties, I dealt with stress better than now in my late thirties. Also, I might add that as I got older, I did not want to cope with stress, I wanted to wind down. It is better for my health and well being.
