If schools as we know them were to cease functioning and all you had was the knowledge and materials you've collected in your lifetime...

And now you had to become a TEACHER (because someone asked you) or out of this necessity what would you recommend for youngsters and adults:

It can be books, magazines, newspapers.

It can be from experiences.

It can be something totally off the scope such as vision.

It can be religious text, etc.

Or best of all, would you suggest that someone to learn things on their own.

Excellent question. I am interested to see how people will answer this one.

first things first........I'd use this to lay the foundation.
