[Just about anybody that has some experience can get a newbie going, but then the safety aspect may be bypassed.]
Truer words have never been spoken. My first mentor (in the 80's) wasn't the best to say the least however I was lucky and didn't have any incidents. Many years later I got to trusting a member of another forum who is well respected and very experienced in many aspects of loading and shooting. I was wrong to trust him in one instance and got lucky again.
I think the hardest thing for a noob is gaining enough experience to know when information is suspect and to act accordingly. Any information I receive from any source is reviewed very carefully and I always draw my own conclusions now. Live and learn as the saying goes!
