Perform. I used to be very shy, so much that I wasn't even able to talk to girls (yes, like the guy in TBBT) and I was always afraid of doing something seemingly embarrassing even if it was not. I cannot even make anything ressembling a dance because I was convinced that people will laugh at me. One day I realized that this was ridiculous so I've started fighting my shyness one baby step at a time. First, I've started wearing sunglasses which I've used consider pretty lame. I was prepared to be mocked out by people but I noticed that nobody actually care! Then I got my first girlfriend which dumped me after one month. I was so angry that I went to this party acting like a douche and I got 3 numbers from pretty girls. So I got the keyword is 'acting'. I didn't like acting as a douche though, so I keep being pretty shy. Well, like seven years ago I've started playing in a christian ska band. What I did then was this: I will disguise myself as a rudeboy with sunglasses and a hat and a checkboard tie so nobody could recognize me and then I will 'act' as a ska rockstar. That worked pretty well, one year later I was dancing like crazy at the stage and three years later I even got some personal fans :D Man, being a rockstar even a completely-obscure one is awesome. So my advice are this two things: 1) Do one little ridicule thing at a time and 2) perform. So when you want to play the guitar don't do it as yourself. Grab some 70's rockstar wardrobe and act like one. For some strange reason rockstars don't get laughed at. So act as one. I've translated succesfully this approach to other areas of my life. Two years ago I got invited to give a talk in the first big web conference in Mexico. I was completely nervous but I knew that this was a turning point for my career so I did it. I watched a lot of talk videos on the web and when I finally got into the stage I stop being myself and acted like a mix between Jason Fried, Gary V and Troy Mclure (the guy from the simpsons). It's funny but acting like an arrogant star boost your confidence. I'm not saying that it works for everybody, just that it worked for me. I'm still not Gary V but at least I'm not Raj Koothrappali.
