I do remember one thing. It took hours and hours, But by the time I was done with it, I was so involved, I didn't know what to think. I carried it around with me for days and days, Playing little games, Like not looking at it for a whole day, And then looking at it, To see if I still liked it. Discipline I wish I had learned about decision trees in high school. Decision trees taught me to think.
Decision trees are useful.
Geometry is not.
