Hi, I heard about PUA and read "Game" and some other books on the subject just about 3 months ago, so I am a beginner.
Also I am 37, Polish ( that is not an asset when you talk to British girls) and I am neither rich nor good looking...And yet, before I ever even heard about GAME, I was going to the clubs alone, and have some successes with girls. As a matter of fact I am still usually going out by myself. When people ask me why am I alone, I am usually saying that I am just new to this area and wanted to meet new people, expand my social circle, and so on...Or, I will start with the story that I was in other clubs with the friends, but they have something important tomorrow and went home, and I decided to have some fun anyway. Actually any story will work, because it is not about what you say, but how you say it.

So, If I can do it, then you can do it too, as it is mostly your inner frame of mind that is important, your personality, confidence and so on...Sure, it is better to have a wingman, but believe you me, it is perfectly doable to to have success going on your own. You can try some self hypnosis and NLP techniques to boost your confidence.
Perhaps we can catch up on some weekend and go out together, hence the wingman problem will be solved.
Best of luck !
