Fill a page today with questions that you don’t know the answer to.
The first question can be about anything at all. For the second question, pluck a word from the first question and include it in the second question somehow. Include a word from the second question in the third one, and continue like that all the way down the page.
Jog your mind with question words like: who, what, when, where, why.
A whole family of questions begin with how: How much… how big… how can…
When you start with What if… a zillion (or two) questions should come to mind.
