I was thinking at this from an ENFP's perspective, but I'd like to hear other people's tendencies. ENFP's are supposed to be pretty flexible when it comes to dealing with changes, with winging it and going with the flow. I can't decide if this really applies to me.
I don't feel very nervous going into new situations at least not any more than I'm excited about it, except if something like public performance is involved.
Plan changes can bother me. Plans loom big in my mind. Either I'm looking forward to them or I dread them. When they don't go through, I'm either crestfallen and have trouble getting past it, or I'm elated and get a giant burst of energy.
When working on projects, I can get rigid. I have a specific vision and am not happy when that isn't achieved. If working in a group if that end vision needs to change because of 'practical' concerns, I can get grumpy .
Conversationally and verbally, I don't even know how to gauge this. I've got an ESFJ friend who's just sharp tongued and quick witted, I usually come up with witty responses, just a couple seconds too late. Of course if you're around him long enough, you figure that most of his responses are 'canned'. Sometimes I'm amazingly on, verbal sparring-wise, and sometimes I'm a mile away.
