The way I think of it, mentors for animation are extremely useless, like taking college classes to learn how to write a song. When you animate you're supposed to come up with you own style and your own methods. Learning everything from someone else would really just make you a carbon copy of them. Animation really isn't as hard as you think. All you need to do is just hunker down and get rid of all distractions. There's no secret method to animation. All you need is artistic skill, patience, and imagination.
