Play with light. Shadows are paint that wont need a brush. Lie down in the back of a car and watch the world go by in reverse. Convex is concave too. Look at your fingerprints and imagine them to be highways. Can you figure the end of the road? Look at rain drops as though they are para troopers in war. Descending fast and fading into terra firma below. Look at ants at work. Especially when they walk in a line and then fill dialogues each time they meet each other as though they are talking to one another. What do you do, to kill time?
