Here is a small routine I used when I started to perform on the street.
1) Sandwich Effect
2) Biddle Trick
3)Two Card Monte or any variation. Maybe do Tivo 2.0 in their hands.
4) Force a Card and then patter it up mentally to just guess their card-easy, simple, effective
5) EDIT: I do not know why i wrote this just ignore it
6) ACR-if you have a Trick Sharpie, use it
You can end with that or you can do any kind of gaff card trick as your 5th trick, and then end with the ACR.
By establishing a routine, you know what you want to do when and you take away the fear of not knowing what you do next. Eventually you might have to switch up the routine, but at that time you will now be scared. By just performing simple hardhitting routines, you can really get rid of your fears.
