Where did Rene Saldana get the idea for the story Jump Away?

It's to know your purpose before you read something because a purpose can:

[he] let his gaze wander to the swirling water of the stream racing madly beneath his feet. a piece of dancing driftwood caught his attention and his eyes followed it down the current. how slowly it appeared to move! what a sluggish stream! what contrasting words are used to describe the stream in this passage?

How does storytelling imagine the future?
