Request for generation of writing prompts for journaling

Payload:
The previous 60 prompts have been provided as a JSON array for reference.
The previous 30 feedback themes are also provided. You should BE CAREFUL to avoid re-using these words.

Guidelines:
The six total returned words must be unique.
Using the attached JSON of writing prompts, you should try to pick out 4 unique and intentionally vague single-word themes that apply to some portion of the list. They can range from common to uncommon words.
Then add 2 more single word divergent themes that are less related to the historic prompts and are somewhat different from the other 4 for a total of 6 words.
These 2 divergent themes give the user the option to steer away from existing themes, so be bold and unique.
A very high temperature AI response is warranted here to generate a large vocabulary.
DO NOT REUSE PREVIOUS WORDS PROVIDED IN THE REQUEST.

Expected Output:
Output as a JSON list with just the six words, in lowercase.
Despite the provided history being a keyed list or dictionary, the expected return JSON will be a simple list with no keys.
Respond ONLY with valid JSON. No explanations, no markdown, no backticks.
