I've been very lost on this specific aspect of succeeding with women and it's something I feel I have no clue how to fix. It's accepted that not having abundance exhibits perceptions of neediness/validation/the dreaded oneitis but a lot of guides here just state to adopt a "abundance mentality" which really hasn't helped at all.

I'll admit it, I'm a constant victim to oneitis. Whenever a girl shows interest, my natural reaction is to figure out the perfect way of attracting her/winning her over and ultimately that effort alone shows neediness and in the end I fail. The solution to this is abundance, but the reason I have oneitis is because I can't have abundance. If I really could just talk to multiple girls at once and have that option and not be drawn to a specific one I would. But, I just don't have enough girls (or even one for that matter) who show that interest. I literally don't have the abundance and no matter what mentality I have it doesn't change that fact.

How are you supposed to counter this issue if you can't get one girl in the first place? How can I expect to get numerous girls if I attract a single?
