i commend you for your lengthy detailed post, and can offer my constructive feedback and criticisms
First of all beware beware beware of delving into a negative reality you dont prefer, where "its hard to get laid in country X" or whatever, because your belief will create bias confirmation and strengthen that reality. Im sure there are many guys who are having great success in eastern europe but we live in a changing world, and its good to remember there is ALWAYS a remedy or solution for every problem. Ive often fallen into that trip in perth western australia, and when i got out of my stupid pity party belief system and went out and took action, used basic systems, i could get decent results. I can tell you probably have negative beliefs like 'im ugly', 'im a dork' or 'im uncool' and the big one 'ITS HARD TO GET LAID' and it comes across in the way you present yourself, you simply dont look or probably project that you are a guy who gets success with women or anything else, and i can see it written on your face
First of all take those glasses and throw them in the bin, they make your face look unflattering and are a feminine style. The way you are presenting yourself and thinking is setting yourself for failure, and i can relate getting nowhere when frankly i dressed like a nobody and therefore felt that way. Get a masculine pair of glasses, Your second photo with your arms out present you in a handsome light, and you definitely arent ugly, i just think you are presenting yourself in an 'ugly' manner and are in an 'ugly' frame of mind. Id start to get some sunlight each day and start to do as many pushups as you can to build up your upper body and look more masculine. My intuition tells me you should cultivate a look of a european artist or russian businessman/mafia type
there are very good points made by other posters, that its all in your head, and ultimately it is. even when i was absolutely positive it was impossible for me to get laid in perth, i knew in the back of my mind there were guys uglier, poorer and lazier than me that were getting laid, and no-time were my eyes opened so much as when i worked retail in a busy area, and saw just how many ugly guys were with hot girls. A great way to overcome this interal lies is to challenge and attack the negative beliefs, and build up positive realities you prefer, and methods like EFT, hypnosis etc can do wonders, ESPECIALLY when you start to work on your core beliefs, which yields miraculous results, especially in areas like "Its hard to change", "Its hard to change my beliefs, im just stuck", or "Its hard to get laid", or "women here are stuck up, im not good enough" its all BULLSHIT
If I was you, id also burn those clothes, because they make you look like an introverted eastern European I.T worker/nerd, especially with your very pale skin, and get a nice white collared shirt, and a nice pair of jeans or linen pants. Depending on your personality type, you could create a look more in-line with a playboy-type, artist, or something other than the vibe im picking up which screams 'average'
id right away download a copy of think and grow rich audio book or book edition, or get the think and grow rich summary, and write out an affirmation list or goal you really desire around sex/love life that really inspires you, and play that on loop while you sleep, and repeat your goal morning and night. doing so has changed my life completely 180 degrees
as for 'waiting for signals', seriously f$#k that idea off completely, if you are a man of action, you dont wait around for 'signals' you take what you want, and i would never have gotten certain girls if i waited for there signal!
Ultimately dont be demoralized, because ultimately all those hundreds of approaches you did shows that you are a serious guy and a man of action, which is to be commended! You are already 98% better than the endless hordes of keyboard jockeys that live on their PC, bandy their opinion and avoid results in the real world. Decide that you are getting a positive outcome from all this, and you will have a positive effect, and when you use the powerful law of cause and effect, as you sow so shall you reap, the results can be magical. The difficulty is that we fail to realize we are taking action in what we perceive as the 'physical world', but ignore the incredibly important 'invisible world' map of the literal realitties that we truly live in. So therefore rather than experiencing the real world we only confirm what we believe is the map, and in NLP they say THE MAP IS NOT THE TERRITORY! This is the invisible 'glass wall' that trips up so many in seduction/pick up and success in general, but there is ALWAYS A REMEDY!
