Public speaking is actually really easy if you don't respect a single soul in that room. I've had an incredibly easy time delivering speeches when I hated everybody I saw and they all thought I did amazing because my disdain was read as confidence. I don't have any tips for you I'm just telling you a fact

I've experienced the opposite effect--speaking is incredibly easy for me when I know and respect everyone in the room. I've never give a more flawless report than when I'm giving it to my treatment team at work, because I know them, and I respect their opinions. I find it really hard to hide my disdain, which is why it could never be read as confidence, like the OP's can ;) Much like the OP I don't have any tips, I'm just giving an anecdote :)
