I’m finishing up a finance degree now and one piece of advice I will give is not to avoid those situations where you may have to speak up in front of people. Trust me when I say those presentations will absolutely suck and crank up your fear and anxiety to levels you’ve never experienced, but if you can just get through it once twice three times etc, you’ll gain confidence in yourself. And in my opinion, confidence in your voice is the only thing that will make any social interaction bearable.
