One Saturday morning, my 6-year-old daughter was making a birthday card for a friend. She was sitting at a small table, and on the floor next to her were about ten crumpled sheets of paper. She kept writing the letter “H” for “Happy Birthday,” then deciding she didn’t like how it looked. She was getting frustrated, and I wanted her to stop using up all the paper.
