Just started a new job last week and it's in a fancy office. The nature of the job lends itself to very slow times that usually last about a month. The nature of the job also requires very strict Internet limitations and no cell phones because we're dealing with very sensitive information.
I spend most of my free time on the Internet or on my phone, so without those two things, I am kind of stuck. We're allowed to read books on the job (obviously not ebooks though), but otherwise entertainment options are pretty limited. What are some good time-passing techniques? I am thinking about trying to learn a new language, but I'd have to do it with a book and not computer software. Any suggestions about other things I can do to pass time?
