You can do sneaky tapping using the finger points. It is just as effective. It is very good to use with simple tapping (see Intro 2).
Gently squeeze the sides of the fingernails with the thumb and finger of the other hand, tap on the side of hand point if you want. You can also tap on the top of the hand, on the webbing between the little finger and ring finger. Everyone will think you are being nervous – not realizing that you are totally calming yourself!
