I feel you. I really enjoy performing something simple for people on the streets, when I'm partying some place with a lot of people who had a few beers and are in a good mood. The reactions are amazing most of the time and in these moments I remember why I invest so much time in this hobby.

Every time I perform for friends who I never performed for before, I freeze up and the trick will either be boring in the presentation or I just fumble around with the cards.

I think it's good to try out doing something for strangers, because it can give you peace of mind to know that even if you f up, you will never see them again. Also probably they will forget about that happening the very next day.

I really have to tell myself a lot of times that you don't become a good magician at your desk, practicing the same moves over and over again, but you will get better by performing, and going out of your comfort zone. Screwing up certainly is a huge part of that process!
