Aim to write for an hour per day. I used to be a teacher, and an hour a day before school was all it took for me to write my first book. Don't get discouraged if a holiday or illness interrupts your writing habit. Just start it up again.

At 16, when I was at Henry M. Gunn High School, I had a crush on the English teacher, and my grades improved dramatically. This great school had only 400 students, mostly children of Stanford professors, and it was more usual to have classes under one of the oak trees dotted around the campus than in the classroom.
