Hypnosis is very easy if you believe in yourself. Family members are a lot harder as they know you from when you were not a hypnotist, so they can convince themselves it wont work.
First thing make sure you know the laws and loop holes, in england it is very easy to get around the laws. Also make sure you know how to deal with Abbreactions, as WHEN this happens which it probably will do at some time, especially if you are doing therapy, it will freak you out but it will scare everyone so be very careful with them.
Strangers are the best to do, you have to remember it wont work with everyone but you should be able to get nearly everyone into a trance like state. im quite lucky as i get to practice at my local pub, the second it got out i was a hypnotist i get requests to hypnotise people, this also makes it easier as they have asked to be hypnotised and so they convince themselves that it will work, in turn they hypnotise themselves. Dont hypnotise drunk people, i had someone lie to me last night, stating they were sober, i tried it with her then relised she was drunk knocked her back out and did it on a barman (who became spiderman for the rest of the evening).
A couple tips that help to impactand kick start hypnosis that i find helps...
"take a deep breath in through your nose, hold it 3 seconds, 3,2,1 and out through your mouth"
do this a couple times as all you are doing are getting them to hyperventilate and become slightly light headed, this becomes a convincer that it is working and helps to bring them down in to the initial trance.
make sure you are VERY charismatic and charming, the more confident you sound the better they will respond to you.
Use terms that although doesnt make much sense, the subject would still try to follow. such as ... "the deeper you go, the better you feel, the better you feel, the deeper you go." this is a very good line to use as it is also a loop suggestion and so would in theory keep them going down further.
My basic form of hypnotising for you to use as an example goes...
"hands on your kneees, feet flat on the floor. hypnosis is very natural, it like you just take a nap on a sunday afternoon.(this is getting them to accept it in advance). ok, take a deep breath in through your nose hold it 3,2,1 and out through your mouth. i want you to concentrate on my hand (i use my hand as a focus point above their heads to get their eyes to become heavy and used to the sleep position). as you concentrate on my hand and listen to my voice i want you to block everything else out, nothing else matters, its just my hand and my voice, every other noise you hear is just another sign to relax more and more, as you sit their and as you concentrate on my hand you feel your eyes starting to become very heavy and you stop blinking and just stare, stare at my hand. i want you to imagine you are at the top of a beautiful stair case. you can see 10 steps going down and each step will take you further and further into a deep deep sleep. i will count you down the each step and when you get to 1 you will shut your eyes and drift off to a beautiful sleep. 10,9,8 your eyes very heavy now 7,6,5 the deeper you go the better you feel, the better you feel the deeper you go. 4,3,2 almost there and 1 sleep(move your hand from above thier head down past thier eyes and towards their lap, this is a non verbal suggestion to sleep and at this point they will just shut thier eyes.)
now obviously i have been going on a fair bit so i will try to keep this next bit short. do some deeping while they have thier eyes shut, do a few tests like arms have become lead pipes and eyes glued shut, everytime you release the command do so by saying it will force you down deeper.
if you want a detailed description of my deepening trances and how i do my tests, wake them up with post hypnotic suggestions or anything just ask
hope there is something in here that can help you out but remember to study Abbreactions and laws etc.
