- I read my note, “fly south for the winter,” and I added, “FOR WHAT REASON?” 
- I thought of loons needing open water for food, and I thought of northern lakes, covered with ice each winter.
- I marked a large X after REASON. 
- I set this card aside to begin a stack of notes that will have a large X after REASON.
- From this stack of X's I will choose a few REASONS that I will write on the cards. 
- By stacking the X’s now, I will easily find them.   
- My Reasons:    • must make sense    • must be true    • must not be silly.
