Do you ever think that you act confident about something (belief, etc...), but are really like pudding on the inside? For me, sometimes I act like I know something as a fact, that I never doubt it's truth, but that's only sort of a surface-level quality. I blame it on . In reality, I doubt myself constantly, and to be honest, am not really sure about something when I say it, even though I pretend to be sure of it. I'm wondering if this is related to dynamic types.
