Hmm, lots of kerfuffle in this thread, so... for the OP:
Out of interest, what exactly is your type?
As individualism has leapt from the Zeitgeist into the very psyche of society, more of us want The Perfect Partner and less of us wish to compromise as time meanders on. Too many of us are enraptured by the thought of finding that perfect ideal: 'The 1'. And that applies just as much to females; thus, there are plenty of reasonably hot girls who'll go to bed alone at night, just in case her idea of George Clooney might show up tomorrow; and she does not want to have some boyfriend in her life should that happen. Oh no. Some can spend absolute years alone confident in the fact that the Brad, George etc. is just around the corner. Which, of course, is bad news for the single males who happen to be stuck in reality without a date.
Speaking of dates - you definitely should try speed dating - it is a lot of fun - even if no one wants to know you afterwards. Or, vice versa.
If you like persons who are not of your race you should definitely consider an international dating site.
I'm reliably informed from those whose smartness excels, that there is no co-incidence to there being so many international model agencies which are stuffed full of russian girls. Thus: The most beautiful caucasians are often Russian. The most beautiful Africans are usually either Somalian or Ethiopian. And last but not least, the world's most beautiful orientals are thai by the way; furthermore, there are more beautiful girls per capita there than anywhere else. And many of them happen to be seeking kind hearted, honest, gentle, mannerly and un-aggressive guys, who are of average/unimposing height (unlike western girls for whom being tall is an absolute necessity for most of them. Indeed, there are even plenty of absolute mingers in most of Europe who'd instantly turn their noses up at a guy who's 5 7" for not being tall enough) and slim, as opposed to muscular and aggressive looking.
Walking up to beautiful girls on the tube or street here, does not work, almost always because if she is as beautiful as you think, then the last guy who walked up to her, to try and win her favours, did so about an hour before you *and* sorry but... yes, once again, she already has an A1 boyfriend. Such a girl is single for all of two seconds in her life and worse for those who are single among us: she knows it...
Joining a yoga class, book club etc. just to meet girls is, let's face it, pretty sad and you'll be "discovered" eventually. And should any success ensue, you'll be pretty embarrassed when she worked out what you were doing there... really. She'll spend too much time wondering what exactly was wrong with you that you went to such lengths just to meet her. (As a general rule: the more attractive a girl is, the less she'll tend to understand what it is like to be single and longing to meet the right partner, as she'll be far more pre-concerned with trying to shake off all the wrong ones who approach her, proportionate to her attractiveness ). Hmmm, at least, that's what I figured was my excuse for not joining such clubs, classes etc., when I was single.
Many settle for second best until the right one turns up down the road, which I do not approve of as such can only lead to disappointment, duplicity, complication, time wasting and heartache down the road. So instead, use being single to your advantage and try and concentrate on the positive aspects of being single rather than dwell on the many, many, many, many, many, many, many, many, many, many, many, many negative aspects of sharing your life with no one. (sorry couldn't resist the reality check there!)
Unless you are an A1 male, hanging out at nightclubs in the hope of meeting 'miss perfect' is the wrong idea. I know, but it took me a long time to realise same, despite others saying so, by the way.
Lastly, you *will* meet someone eventually, whatever you do. Nonetheless you'd do well to learn the traits of all the DSM IV personality disorders as it will save you a lot of time in the long run if you can rapidly spot the many 'train wrecks' among fellow humans - but definitely do so long before you become too mentally involved.
Good luck. I hope my advice was helpful...
