I perform to family and friends.
Oh Glorious news, I bet you like being that one guy in your family ^.=.^, I was like that at one point the nervous thing there is a story that I know of that might help in this situation.
It reminds me of my earlier time hand turning bowls on a lathe. When I would start the bowl I would do it flawlessly and with little effort. But I always got the jitters when it got down to the last few centimeters of wood, and end up breaking the bowl. My teacher made me start over again each time I broke it. Although I broke the bowls *cough cough* 87 times, each time I would get farther and farther and more confident. But as the bowls got thinner the easier they were to break with the slightest of jitter. I am now on my 107 bowls and seemed to have gotten stuck at the last few millimeters.
My teacher stopped me before I started to make the next bowl and said “Stop and relax take a deep breath, now let it out and visualize yourself and your goal. In your head visualize your process as you shave the wood away.” I was skeptical at first but did as I was told. I still have that 108th wooden bowl today.
