One of the main components of an "emotional style" that one might have is how long a positive feeling persists. If you give a talk that goes well, for example, how long does that "afterglow" last? For me, it is quite long. Even minor positive things can keep me in a good mood for a long time. At one extreme would be people who have good things happen to them and do not register them as positive at all, who immediately discount them, looking for the negatives.
Anyway, what a lot of people mentioned to me after my talk in Córdoba (which I am still in an afterglow about), is that what came through is my passion for Lorca. This was a surprising result, because it was not my conscious intention at all. I thought that what would come through was my iconoclasm. Nevertheless, I have to accept what the audience said. This was a conference of about 40 people, and I think about 90% of them congratulated me individually on the talk.
A little passion goes a long way, in a medium in which passion is not the most expected element.
