Take the "get to know women as people first" advice with it implication that instead of approaching women for relationship, one should join clubs, societies, hobby groups where he can meet women and things develop organically , where a spark might happen later on, women themselves claim they can only fall for a guy after they get to 'know him'...

Yes, if you're an average girl, that is single, good chances are that your (single) male acquaintances/friends will eventually ask you out or express a desire for something more (it happens so frequently women now complain about it being annoying).

If you're an average guy this is different; a guy meets girl, they click personality wise, he thinks they got a spark going on, she sees him as a brother**.** His problem is not even that he's unkempt or ugly, but that his appeal is limited to a small percentage of women, that are indeed out there, but are few and far in between. Going the 'meet women through hobbies/interests and lets see where this goes' route of ambiguity is not only time consuming, it becomes very emotionally draining after the first few 'sorry, I just don't see you that way'.

Women's general disinterest in the average guy is what is forcing him to 'play the numbers' and do a little bit of 'grinding' before he reaches the one that will reciprocate his feelings.
