Everyone is creative - especially when there are no rules.
This is your book to use as you want. You can skip exercises. Rip out a page. Share with a friend. Ignore instructions. Do one prompt multiple times. Draw in the bath. Draw at work.
Make a badge. Do a tiny painting. Do a huge painting. Cut a hole in the page to see your art on the following. Have a party (that's not really a prompt). Collect something. Stick it to the page. Paint something using only blue. Draw what you see. Make a collage. Write down overheard conversations and turn them into comics. Sketch your emotions. Make ink blobs into characters. 
The only thing you need to do? Keep having fun.
This Book Has No Rules is a sketchbook of creativity prompts for a day, a month, a year, that will help you leave aside the productivity drive, put down your screen and pick up a pencil to draw and create the way you feel like. There is no marking, no scores and no homework - only creativity, your way.
