In doing we learn.

It is shocking to find how many people do not believe they can learn, and how many more believe learning to be difficult. Muad'Dib knew that every experience carries its lesson.

We can say that Muad'Dib learned rapidly because his first training was in how to learn. And the first lesson of all was the basic trust that he could learn.

Proper teaching is recognized with ease. You can know it without fail because it awakens within you that sensation which tells you this is something you have always known.

The wisest mind hath something yet to learn.

One learns from books and example only that certain things can be done. Actual learning requires that you do those things.
