I'm new to this, and I had a few questions about getting into a trance.

1)How much concentration is required to actually go into the trance? My mind has been wandering during the induction, and even during the suggestion, so I don't know if I'm actually in trance.

2) Do some inductions work better than others for some people? Could mixing and matching inductions help if I just can't get one file?

Thanks.
