Based on the provided story, I have evaluated its tragedy and comedy elements. Here are the results:

- **Tragedy Degree:** There are some emotional setbacks and challenges in Peter's life before he finds the book that helps him transform his perspective and life, but they are not extremely profound or deeply tragic.
- **Comedy Degree:** The story is relatively light-hearted and has a positive and uplifting ending, but it does not feature strong comedic aspects or an extremely happy ending driven by humor.

Given these aspects, here is the scoring in JSON format:

```json
{
  "TragedyDegree": 4,
  "ComedyDegree": 6
}
```
