Without writing down a single number, describe some of the numbers in your life.
Write about numbers that you keep track of and numbers you are curious about. Numbers that you remember and numbers you always forget.
You can tell how to find out certain numbers, or which numbers will never be known.
Are there numbers you like and dislike? What can you do with a lucky number?
Fill a page with numerical ideas without writing down a single number–except for the date, of course, along with your signature and a title.
