one's approach to conversations and discussions matters, whether one is there to assert dominance and gain validation or one is there to learn, to find out and help. one must remember it's not about them it's about the project or the bigger picture and they are just the means and not the end.
so whenever you are talking in front of the camera of an audience, just be yourself and focus on why you are there and do justice to that cause. don't be rigid and scared of judgement, good people care about the important things, a seasoned runner won't judge you, and what the bystanders think doesn't matter. don't look at yourself through someone else's eyes, it doesn't help. thus you don't have to force a smile or conform to a certain accent.
