What did Jamal learn from William Forrester?

I would say Jamal learned quite a few things about William Forrester. Jamal learned how to write, and that was the most important thing. Throughout this movie his writing is what got him recognized throughout most things. William thought Jamal one of the most important things when it came to writing; never think just type! When you spend too much time thinking about what to write, you no longer show as much intrest in what you were planning to write in the first place. William proceeded with an example and began to press on the type writer, and from there just couldn't take him off of it. Jamal learned many qoutes and sayings from a variety of authors and books. Jamal was also taught to write what he felt with every detail. William promised Jamal to teach him everything he knows about writing and to make him a tremendously good writer with only one thing in return, that was to promise never to tell a soul that he himself was still alive or that they had any type of communication with each other. Jamal never broke that promise, and with that, Jamal  succeded on becomming what William promised him to be from the start.
