How to improve my confidance?

Ok, confidence is an illusion. Everyone is nervous at times. Remember to talk a little slower ( it makes you sound more confident and less chance of misspeaking). Walk straight. Sales people wear blue but black clothes represent power which would make you look confident. Smile, everyone likes to be smiled at and it makes you look approachable and friendly. Most of all remember you have the power to control yourself and your feelings and thoughts and emotions. So if you think and act confident then you will appear that way and people who don't know you do not know how you acted last week so you can start been new right now at this moment. Only you have the power to create your future so create the future that you would like. You can do it and you will do it, so now GO DO IT! Good luck!

I actually changed the way i appeared physically. I learned that the way people walk can tell you a lot about them, and before, I'd always walked with my head down looking at people's feet (so I could predict where they were going to step so I could move out of the way because I walk fast), but then i started walking with my head up for a couple days and then people started to move out of my way, then after that I leaned my shoulders back a bit and the mutual respect I got for posing myself as if I was on the same social level as them made me feel more confident. It really is just an illusion. i have to work on talking more loudly and clearly though. You may have to go out of your comfort zone for this, but what doesn't kill you only makes you stronger!
