I was wondering if anyone had any ideas for building self confidence and/or coming across more self confident? I find I either have in the back of my head "what if I look anxious?" or "what if I look incompetent?" particularly at work, sometimes in front of large groups. Also I am small and my voice is small and that does not help. Lots of times people can't hear me and I don't command much authority. Any suggestions on how I can work on this?
