What if Jack decided to be a “good boy” and obey his mother’s command? What if he let the fear of what others may think of him stop him from taking a chance on those magic beans?
We would have no story. There would be no magic, and no one would ever know that Jack or his cow even existed.
The point is to go for the adventure! Believe in your dreams, and risk it all! Why not? What do you have to lose? None of us are getting out alive anyway. Why not go for the adventure, and have a good story to tell?
