Actually, a fairly balanced mix of cautiousness and impulsivity. I try not to plan things too much because the more I plan the more things go wrong. At the same time, due to anxiety issues and parenthood, I'm very cautious about things... cautiously impulsive, I would say.
Caution is something I have a lot of. For some reason. More so in social situations than other areas. But I can get in a random mood, usually when I'm hanging out and having fun with friends. Then I can do some pretty impulsive things.
Every time I do something impulsive, it either blows up in my face - like last week when I bought a dress on Etsy literally the moment I saw it, and ordered the wrong size by accident - or someone yells at me because I've done the wrong thing.
