I always found target number of books a bit strange. I tend to get books in the 5-6hr range (shout out to https://howlongtoread.com/). When it comes to books that would take me like 10-12hrs it starts to feel a bit daunting. With my sched it takes me like 2 weeks to finish a 5-6hr book coz of my schedule. A 10-12 hr book would probs take me a month. Source: over 1 year ago
