Inspiration from any quarter could be fantastic. As shown in this story Jerry, who didn't even want to bid or pay for the box finds the letter. The message in the letter sets his dream high and gives his life a sense of purpose and direction. Follow your heart, seems to hold the key to happiness.
There is a lot of stuff here depicting the human psychology. How emotions as hope, anticipation, a sense of fulfillment and the means to dream high work in the mind is well depicted.
A message and a means to find happiness are well conceived my creating a story format.

Dialog, action and setting are appropriate.

Write on!
