Hey guys, your teenager here again. I've previously asked a question and received some amazing advice, so I really thank you guys for that.

How can I enter proper monk mode? I already know that its the conventional "shut off internet, work out, read books" etc, the only thing is that I'm not sure what to fill the majority of my free time with. Working out takes around two hours out of my day, and with the internet gone, I'm not sure what else to fill that void between school and sleep. I know I should be reading, but what? What books would you guys recommend? Thanks.
