This one took a while for me to get down. And is really tough to balance... Like 90% of my job is conveying confidence to clients, a decent bit of which is just confidence in me. So on the one hand you do legitimately have to be like "I'm the best at this and your company needs me", but on the other hand if you overdo it you end up basically playing Ellis from die hard or Jared Vennet or somebody, which turns a whole lot of people off too.
