What everyone else has said so far I also find to be very true.

Another I'll add is that a good mentor or teacher calmly and gracefully handles those who challenge them by says things like "this is boring" "what's the point?" "I don't care about this" You get the idea. I'm talking about those who look at this program and get a sense that it's supremely boring and/or a waste of time. A good mentor can battle it out with that person and win.
