In the early 1980s I ran a backpacking guide service which I called Walt's Bush Survival School. I ran it literally out of a backpack and used a contact phone number of a friend with a house and, well, a phone, the two things I didn't have. On each weekend I took out from one to three people and trained them in the following wilderness skills:
Knowledge of backpacking equipment
How to survive on edible wild plants in the Watauga mountains
How to read a map
Emergency shelter construction
Cold weather camping
Nature awareness training
The voluntary simplicity philosophy
The last included this paragraph: "There needs to be an alternative lifestyle available to people other than the usual American way of life. By camping in the forest, by carrying everything on one's back, by finding contentment in simple things, and by respecting the natural way of life, a person can begin to understand what it means to be independently wealthy and therefore better able to embrace the simplicity philosophy."
In the time I ran this impromptu school, I took out a dentist and his wife, a group of high school kids, and an assortment of weekend hikers and backpackers.
