A turning point can arrive on an event or a thought.
You might notice a turning point as you pass through it, or only come to understand it in retrospect.
Write the letters of the alphabet, in any order, down the center of the page.
Choose a word that begins with each letter. On the left side, write a phrase or sentence that uses that word and was true before the turning point. On the right-hand side, use the word to write something true from after the turning point.
Give your work a title and write the date on it too.
