Trying hypnosis

I've started looking into self-hypnosis to see if I could use it to get over some of my self-made blocks to increase my progress (I assume I'm making some).  Anyway, the other day at the state fair I ended up on stage at the hypnotist show and really, really thought I was not a good candidate because I was positive I wasn't hypnotized.....wellllll, the post-hypnotic suggestion he gave--that I would burst into laughter whenever anyone would shake my hand after left the stage--worked.  People kept reaching for my hand as I walked back to my seat, and I would grab their hand and laugh hillariously!  Guess there might be hope for me yet.  It would be nice if I could get out of my own way!
