There are three main categories within a typical ThinkBook:
a) To Think List
Like a to do list, you write and track things you want to think about
b) Possibility Thinking Pairs
There are over 30 possibility thinking pairs. Each possibility thinking pair consists of a visual insight that can trigger an "a-ha moment," followed by a related question that will help you think about the insight in the context of your situation.
c) To Thank List
As the name suggests, here you keep track of who you want to thank, and why. Once you do, you can mark them off the list.
Plus, of course, you have lots of empty pages for you to write whatever you want.
