I don't see how its possible to be bored in this day and age. I already have more video games, books, tv shows and movies to cross of my list than I could go through in 3 lifetimes.
There's also so much to do and see in this world. I made a list of my favorite activities and all the things I want to do/try, its called my "Weekend Activities" list. Every weekend I do something new. Then there's spending time with the people I enjoy...
IMO, there is no excuse to be bored these days.
If gaming is your thing and you have a decent PC, I HIGHLY recommend DayZ. Its still in Alpha and its rather buggy, also plagued by dupers/hackers, but to date no game gets my heart pumping more. The interactions you have with people, the inventive ways people decide to play the game, the YouTube videos... DayZ is just... the most promising game I've ever played. I cannot wait until the next patch, almost every week they add a ton of content. Also, its the most hardcore; Gotta love permadeath of your character... really makes your heart pound when being shot at.
If you've never heard of it, watch this to get an idea of what its like:
I've got over 700 hours into the game, but have definitely spent more time just watching people like JamJar or Mr. Blackout play the game.
