Fake it till you make it

I am very confident when I present. I learned how to cope with being comfortable while presenting. I think of it as presenting to big group of friends, whether I know them or not. Presenting projects in classes helped me become more comfortable with being able to present in such big groups too. Although, I'm not confident with my posture and how I fidget with things. Like the video said, I just have to fake it till I don't fidget and have a better posture in presenting.
