I'd love to see a form of Reading Challenges made for a single user. I like the idea of Reading Challenges, but I struggle to find ones that encourages me to look at something new without throwing me far out of my interests.

The closest I can find to this is To-Read Pile Suggestions for Plus members. In this case, the idea would be to go outside of your To-Read Pile and stick you to a schedule within a time period, like weekly or monthly.

Like Recommendations and Preferences, being able to keep genres and topics excluded would help keep a challenge within a person's comfort zone. For example, I don't want a reading challenge suggesting me to read religious works. While that may be outside of my comfort zones, that wouldn't be a very enjoyable challenge. Being able to randomize based on category, maybe even to-do pile, would be helpful as well.

Possible ways this could be handled:

- If my statistics judge that I read a lot of fiction books, my personalized reading challenge will only give me fiction books.  

- If I read a lot of fiction books focused on science fiction, I might be recommended a nonfiction book detailing the evolution of science fiction media.  

- Categorize based on Up-Next and Recommendations? "Read this book from your recommendations this month, continue this series this month, etc."  

- Specify genres you'd like to focus on "Only recommend me horror and thriller books for this week/month/year."  

Alternatively, or as an add-on, have community Reading Challenges suggested to you based on filters that match your interests.

From there on, you could edit your challenges to better fit who you are than what a robot things you are.

I'd love to hear further expansion or alternate considerations on this idea! I imagine this would be far, far off into the future, but a person can only hope!
