really, this.
Internets,
Cooking,
music
I read books, comics and manga..... on the internet.
read a lot of esoteric stuff and conspiracy crap
I also study and implement this Internet Marketing stuff when I have the chance or the money.
I used to shoot a LOT of pool. Like 4-8 hours a day. No decent pool tables that arent in redneck honkeytonk klansy bars for 100 miles of me now, though.
I also take walks and snap pictures of cotton fields out of boredom.
Life's pretty boring, actually.
But like any other prison, you either break or study and better yourself. If you can survive the isolation, you can only thrive in the real world.
