I go through those cycles too. I'll have spells where I just can't get a number close, or a friendly smile from a gal no matter what I do, how relaxed I am, etc. Then, I'll have periods where, for no reason, smiles, conversations started by women around me, etc..
I know people here will try to explain it, saying that I was previously trying too hard, then I just did not care and the lack of response on my part generated their attraction, etc. It'd be nice to have a webcam, and get your opinions.
However, IMO, it's not this. During the dry spells, I'll think back on the day when I had women around, and was just into my thing, or was otherwise aloof; nada, nothing. Being who I am, I'm well versed in statistics, and it's largely a consequence of the numbers. If you walk up to a slot machine, and play for a long time, expect periods where you win no matter what, then expect periods where the machine just eats your money heartlessly. This may be the same deal.
So.. in part, I'm saying to not get discouraged. The down cycles may be because of things external to you. You may be the best looking and most charming guy they've seen in a while. However, you could be getting a group of lesbians followed by a group of happily married's, followed by a group of men haters...:cuss: Then, you may run into a spell of women who've grown and reflected that they really need to be more available to decent men, women that are surrounded by many HBs and have not seen many attractive men, Valentines day or another holiday is coming up, etc.. :woo:
Whatever.. I do my best to measure my success by what I control, my skills, making the approaches, improving, etc. I claim no responsibility for a woman's choices.
