Boredom during the 10d
This month I'd have my first 10 days of Vipassana and after re-reading daily schedule I have concerns of what to do in a free time: 90min of breakfast, 120min of lunch, 60min of tea time, and especially all after 21:30?
Besides that I eat & drink fast enough I'm an 'owl' ie going to sleep after 2am is my regular thing.
What do you recommend to make yourself busy with all that enormous free time there? Going out isn't allowed. Books & journals also are not allowed, but maybe I can bring Rubik's cube and use it only in my room?
Because of so many restrictions I understand why it's challenging for many not to go crazy and so why some can't make till day 10
