When I was little, "Frog and Toad are Friends" by Arnold Lobel was a classic book for our family. Not only did I find their adventures amusing, but I enjoyed the contrast between the optimistic Frog and his pessimistic Toad friend. I found comfort in the fact that I was nothing like that grumpy, unmotivated Toad.
And then I recently read "Tomorrow" in "Days with Frog and Toad". In this story, Toad has an epiphany that if he does his work today, he'll have more time tomorrow to do what he wants (i.e. sleep).
And then I realized I have more in common with Toad that I thought.
