Why is it so hard to find love these days?

Am I supposed to take a proactive stance here and just go on dating sites or ask guys out myself? Or should I sit back, relax, mind my own business and hope that at some point some smart guy will realize what an accomplished self-confident woman I am and will not be able to resist approaching me? HAHA, Seriously though, I am kinda losing all hope here, I dont think i can ask guys out, I am to shy to do that and its not my idea of how things should be but, guys just do not approach me. I dont know why. I know I am not a model but i am not ugly either, i dont laugh my head off every 5 seconds but i dont think i am necesarily coming accross as too serious or snobbish. So what is it, WHAT IS IT damn it?? I am 26 and been single for 2 years at this point I basically feel as though I am invisible to men. Any advice as to how to break this dry period?? Any girl that has gone through the same but managed to find someone nonetheless?
