I wonder how much time I've wasted:
Learning useless information, specifically advanced mathematical equations. (I mean, don't get me wrong, I'm sure Pythagoras was a great guy.)
Watching awesome Japanese cartoons.
Watching dorky American cartoons.
Watching awesomely dorky Americanized-Japanese cartoons.
Finishing the song playing in my car when I get home.
Pooping. (Let's be honest, it's a waste of time. Colostomy bags are the way to go.)
Capitalizing and punctuating when it isn't needed or incorrect.
Wall-staring. (It's a legitimate form of entertainment)
When you think about it...I could have used most of that time to watch more Japanese cartoons.
