Tracking my book reading time is one of the most recent pieces of data I have begun collecting. It is quite impossible to see how long it took me to read books before I started tracking it as every book is read at a different pace. I only started tracking it during the summer of 2023, so it will take a couple more years before I get some good information out of it like the other two topics.
I got really into reading during 2023 and 2024, but at the end of 2024 I started college. I felt like there was no time to read during that time and it shows as 2025 had under 50 hours of reading compared to the almost 300 hours the previous year.
