text: A big part of confidence is in the way you carry yourself.  Stand up straight.  Think of a straight line going up your legs and spine straight to the top of your head and align your stance to it.  Smile when you see people, and look them in the eye (briefly, don't stare).  Think of yourself as the confident person you want to be, and imagine the positive reactions of those around you.  Make a practice of this regularly.  You may not only find this enjoyable, but there is scientific evidence it actually works to boost confidence in people who practice it regularly.  Good luck!
