This is the story of a caterpillar changing into a butterfly. He has no patience...
This book has been published so you can get a copy now.
He doesn't even know the process for becoming a butterfly. Another explains it to him and says it will take two weeks. He can't stand it. There's nothing to do while he waits. He breaks out of his chrysalis but it's too soon.
He makes another one and waits. This time he's successful and becomes a butterfly.
The part that tickled me was that he kept asking if it was long enough yet until all the other butterflies tell him to shut up. It's like a child saying, "Are we there yet?"
