Yeah, single's getting to me too. Whatever.
I'm single, and have been for... oh, nearing a year now? In ways it's nice, since I'm finding time to finish projects I've had difficulty setting aside time for before, and doing more of the things I've been meaning to do, like backpacking this weekend! Woo hoo! Still, there are definite trade-offs. I've found myself sorely missing the close contact... It's a simple thing, but falling asleep on a futon on the floor is a lot nicer if you've got someone to hold. The roommate continually talking about his boyfriend doesn't really help things either. :/
I think a good lot of people out there are single, quietly waiting for someone to come into their life, or approach them with romantic interest, etc. That rarely happens though... rarer still with guys, since there's a cultural expectation of guys "making the moves". If you want to circumvent the whole silly thing, though, the best thing to do is to build a network of friends... as you go through your day, chat with people, and don't be afraid to let them know what sort of person you are, just as you get to know them. Maybe you'll find someone you have a lot in common with. If you find yourself interested in one of your friends, then approach them about it.
For all the "Friend Zone" stuff that is purported, personal experience says that the best relationships come from preexisting friendships. So yeah, give it time, but make sure you're actively getting to know people too. Otherwise, you'll just do a whole lot of waiting.
