"In myths and movies, the mentor can play a few roles: they bring the hero a magical gift, teach them how to use a special tool, or help the hero get unstuck. In a presentation setting, the presenter is the mentor. Our role as a presenter is similar to a mentor. We should be brining something of important value to our audience, they should not leave empty handed. There should be something useful and somewhat life-altering that we give them. It's not very often that we sit through a presentation and feel like we've sat at the feet of a mentor, but we should."
