Specific challenges

For me, the number of books I read isn't relevant. I've read brief novellas that capitvated me and been captured by the detailed evaluation of a 1,000 page piece. I wish Goodreads would allow for custom challenges. Every year I set a new goal to read 5 of a specific genre. History, memoir, classics, science... I wish that I could use the app to track my personal goals each year. I often forget what previous year's goals were. Also, a pages read goal would be interesting. What would your personal goals be?
