The central fact of your education is this: You've been taught to believe that what you discover by thinking, By examining your own thoughts and perceptions, Is unimportant and unauthorized. As a result, you fear thinking, And you don't believe your thoughts are interesting, Because you haven't learned to be interested in them.
There's another possibility: You may be interested in your thoughts, But they don't have much to do with anything you've ever been asked to write.
The same is true of what you notice. You don't even notice what you notice, Because nothing in your education has taught you that what you notice is important.
