This will be my last attempt at helping some guys here since all my other posts got deleted by admins despite getting tons of upvotes and all base on my own experience sleeping with 150+ girls now. I am doing this mostly because I have some time to kill so let's jump right in.

supply & demand

If you are having trouble getting laid you are likely in an area where supply (e.g. other guys) is high or demand is low (e.g. you live in a sm town). Move to an area where supply and demand works in your favor. Myself being tall an blonde, am not a rare commodity in my home country, but I am in countries where blonde guys are rare. Find your ideal market and stack the odds in your favor.

price elasticity

Depending on a girls sexual availability she might 'settle' for less and give it u easily (e.g. she has been super horny) or give you a very hard time (she has unrealistic standards for example). Ideally, you first check her availability through physical and verbal escalation to decide how much effort she is willing to invest to be with you and how difficult or easy it will be.

target audience

Don't let society dictate what type of women you should be attracted to. Find the common denominators between girls you are attracted to, and make sure it resonates with you and the man they want to be and you already are or will be soon. Then find out how to meet more of them.

product dev

Talk to girls all you want but if your product sucks (i.e. you are a loser that looks horrible and you hate your life) it doesn't matter. Create a product people want (ie. chase excellence) and you will be in high demand guaranteed.

marketing

In business you don't rely on 1 single marketing avenue for your customer acquisition so why should you in real life? Diversify how you can meet women; go to classes you enjoy, attend social events, use the dating apps, and go to clubs/bars/parks/streets/ whatever.

sales

When they want to buy - skip all the BS and just close already. Don't oversell it because the customer is impatient and just wants it now, you don't need to 'sell yourself' anymore - if at all.

retention

Keeping customers/girls is about keeping them happy. Depending on your type of relationship that might mean just good sex, or a lot more like quality time, attention, and dinners. Some thus will simply leave you because their expectations changed or you mismanaged it.

churn

Some simply ghost you without an explanation. If this happens all-the-time you need to zoom out and find out what is going wrong (i.e.g your product, your marketing, your target audience etc.) and fix it.

value

Anytime you don't provide enough value they will leave. This is fine, you don't want all girls to stick around. Just be aware that if they perceive your value as low or diminished, they will leave.

volume

Talk to 5-10 girls a day randomly and you will have a great dating life. Talk to 5-10 girls a month and you will have a mediocre dating life. Talk to 5-10 girls a year and you will have hardly any dating life.

switching cost

If a girl already has one or multiple guys she is talking to (i.e. invested in) you might be just what she wants but in her mind her switching costs might be too high (i.e. the required effort needed to go from what she has now to the new guy). Be aware this is at play and don't take it personal.

sales funnels

always be closing :)
