I’ve got chests full of diamonds and a huge fortress of solitude in my singleplayer world. I’ve found the End Portal and I’ve got enough eyes to activate it. But why bother? Alone, I don’t stand a chance against the Ender Dragon anyway: I’m just not that good a player. And it doesn’t matter how much time I spend enachanting all of my stuff, it’s never going to be good enough.
So there’s no point. I’m sat here, alone, and I’m not achieving anything anymore. Sometimes I just want to delete the world and get it all over with. It’s not like anybody will miss me.
