Project 50 Books

This challenge is not from me originally, I found it at a German blog. It's a combination of a buy ban, with the intent on saving money, and a tbr pile challenge. Simply put: You have to read 50 books before you are allowed to buy new ones. You can still get new ARCs and freebies though, since they come with no cost.

You can just read towards the goal, or you can add certain categories with a quota to fulfill along the way to make it more interesting and/or more challenging for you.
