Singing in the car to your favorite music (must have singable lyrics! NO WUB WUB). I have been using this for a while to get myself in state, but I have found it massively boosts my confidence along with getting me over abit of AA, as part of it for me is to sing even at traffic lights, who cares what others think your just having fun!

One side effect I have noticed is that you will speak more fluently, in a deeper tone which also helps in attraction and stops stuttering abit if you suddenly get nervous.

Just a quick tip I thought I would share.
