Mind the mundane swearing.

I am studying my arse off, and I legit need something nice to do in my free time. I have gone through a sh*tload of riddles and crosswords, but it has gotten boring because I no longer see a good riddle, a difficult one that will take me, say, a week or something to solve. One that will take a long time to come by.

Please help.

Your distressed,
