equine education---how did you learn?

As I read this board and some homesteading boards I realize that many want to use draft horses but have no experience with equines and need to learn the basics.
My life has almost always been about horses, and i'm a pretty good all rounder with many horses and ponies.

I've been sharing some knowledge with some folks and wonder if I should create a workshop for people to attend to learn some basic horse keeping skills. I can speak to shelter and nutrition and health, riding and driving and animal selection.
if I were to pursue this i'd get a lot more experience with logging and plowing, as I've barely touched on either one.

Or maybe I get myself a decent pair of mules and travel around doing demos on farms or farmers' markets and such.

Think anyone would pay for a weekend or month learning?
Maybe go wwoofing with my team around the country someday?!

So if horses haven't always been in your life and you use them on your place, how did you learn and how do you wish you could have learned?

I learned by caring for a woman's three horses while she was out of the country for five months. I spent a lot of time frustrated and reading on the internet, but I'm five months transformed three skittish horses, one dangerously underweight and another quite portly into three healthy riding horses who were fun to work with. I would have loved to have someone to teach me how to "read" horse, but daily time with them does wonders for the learning speed.
