Ah the typos abound, yes I mean don't

If you don't work with real people on "real" problems then the new hypnotist will not gain the experience they need to be successful at this craft. I recommend charging as well for said work. It doesn't have to be a large sum. In fact I knew one hypnotist when they were first starting out who would see clients only if they donated to a charity (instead of paying directly). For better or worse people tend to place greater value on what they pay for as opposed to what is free. Having some base requirement creates a greater buy in for the change to occur. It increases the clients motivation.

I encourage my students to go out and start working with people. I have seen far too many people who become so afraid about working with others that they become seminar junkies. They never have enough training to go out and realize their dream. They say "I'll start after I have this next training" but it never happens.

With that being said I layer up a huge amount of suggestions about ethics with my students. There are some things that are much easier to work through than others and I encourage them to recognize that and stay within their ability and ethics. I also only certify those who have passed their practical exam, exhibiting the ability to work with others in a way that at the very least does not cause harm.

A good hypnotist isn't made in the training room, they grow out of experience
