My biggest reason why i get nervous is because i CARE about the results. So if im getting nervous i try to think thoughts like, "i don't HAVE to win right now, this match", "Its OK if i loose". When I really feels this I dare to do offensive and sometimes crazy strokes BUT im relaxed and not nervous at the same time and therefore my shots usually get in. Maybe you are nervous about other things, but I think if you can go into that feeling that you NOT CARE about whatever you are nervous about your nervousness will disappear.
