I spent around 40 days int the hole from my 2 year sentence. I read the first time, but they only allowed 1 book at a time and I ended up re-reading same book a twice a day. Then second time they only allowed to read 1 hour a day. I ended up walking in circles and imagining various book plots and yc startup ideas.
